Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147387996, here are decompositions:
- 37 + 2147387959 = 2147387996
- 139 + 2147387857 = 2147387996
- 157 + 2147387839 = 2147387996
- 277 + 2147387719 = 2147387996
- 283 + 2147387713 = 2147387996
- 349 + 2147387647 = 2147387996
- 367 + 2147387629 = 2147387996
- 613 + 2147387383 = 2147387996
Showing the first eight; more decompositions exist.
