Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147485712, here are decompositions:

  • 139 + 2147485573 = 2147485712
  • 331 + 2147485381 = 2147485712
  • 523 + 2147485189 = 2147485712
  • 571 + 2147485141 = 2147485712
  • 751 + 2147484961 = 2147485712
  • 991 + 2147484721 = 2147485712
  • 1033 + 2147484679 = 2147485712
  • 1171 + 2147484541 = 2147485712

Showing the first eight; more decompositions exist.
