Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147489908, here are decompositions:

  • 59 + 2147489849 = 2147489908
  • 89 + 2147489819 = 2147489908
  • 191 + 2147489717 = 2147489908
  • 257 + 2147489651 = 2147489908
  • 269 + 2147489639 = 2147489908
  • 467 + 2147489441 = 2147489908
  • 617 + 2147489291 = 2147489908
  • 701 + 2147489207 = 2147489908

Showing the first eight; more decompositions exist.
