缘由C语言 验证哥德巴赫猜想(奇数)-编程语言-CSDN问答

void 哥德巴赫猜想奇数()
{//缘由https://ask.csdn.net/questions/7570770?spm=1005.2025.3001.5141自7始奇数都是3个质数和，奇数-2起求质数验证。
	int a = 5, aa = a,aaa=0;
	while((a += 2)<100000)
	{
		aaa=aa = a;
		while (aaa > 1)
			if (质数判断(aa -= 2) && a - aa > 2)
				cout << a << "=" << aa << "(" << a - aa << ")+", aaa = 0; else;
		if (a - aa == 4)cout << "2+2\t";
		else
		{
			aaa = aa = a - aa, --aa;
			while (aaa)
				if (质数判断(aa -= 2) && 质数判断(aaa - aa) && aaa - aa > 1)
					cout << aa << "+" << aaa - aa << "\t", aaa = 0; else;
		}
		cout << "\n";
