Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147487812, here are decompositions:

  • 13 + 2147487799 = 2147487812
  • 31 + 2147487781 = 2147487812
  • 61 + 2147487751 = 2147487812
  • 109 + 2147487703 = 2147487812
  • 163 + 2147487649 = 2147487812
  • 241 + 2147487571 = 2147487812
  • 271 + 2147487541 = 2147487812
  • 409 + 2147487403 = 2147487812

Showing the first eight; more decompositions exist.
