Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147489930, here are decompositions:

  • 13 + 2147489917 = 2147489930
  • 31 + 2147489899 = 2147489930
  • 109 + 2147489821 = 2147489930
  • 277 + 2147489653 = 2147489930
  • 457 + 2147489473 = 2147489930
  • 631 + 2147489299 = 2147489930
  • 727 + 2147489203 = 2147489930
  • 787 + 2147489143 = 2147489930

Showing the first eight; more decompositions exist.
