Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147567918, here are decompositions:

  • 31 + 2147567887 = 2147567918
  • 151 + 2147567767 = 2147567918
  • 229 + 2147567689 = 2147567918
  • 241 + 2147567677 = 2147567918
  • 337 + 2147567581 = 2147567918
  • 547 + 2147567371 = 2147567918
  • 607 + 2147567311 = 2147567918
  • 739 + 2147567179 = 2147567918

Showing the first eight; more decompositions exist.
