Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147387016, here are decompositions:
- 7 + 2147387009 = 2147387016
- 13 + 2147387003 = 2147387016
- 29 + 2147386987 = 2147387016
- 163 + 2147386853 = 2147387016
- 263 + 2147386753 = 2147387016
- 283 + 2147386733 = 2147387016
- 317 + 2147386699 = 2147387016
- 349 + 2147386667 = 2147387016
Showing the first eight; more decompositions exist.
