Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147387064, here are decompositions:
- 5 + 2147387059 = 2147387064
- 47 + 2147387017 = 2147387064
- 61 + 2147387003 = 2147387064
- 181 + 2147386883 = 2147387064
- 211 + 2147386853 = 2147387064
- 307 + 2147386757 = 2147387064
- 311 + 2147386753 = 2147387064
- 331 + 2147386733 = 2147387064
Showing the first eight; more decompositions exist.
