Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147528806, here are decompositions:

  • 29 + 2147528777 = 2147528806
  • 167 + 2147528639 = 2147528806
  • 263 + 2147528543 = 2147528806
  • 509 + 2147528297 = 2147528806
  • 677 + 2147528129 = 2147528806
  • 719 + 2147528087 = 2147528806
  • 827 + 2147527979 = 2147528806
  • 947 + 2147527859 = 2147528806

Showing the first eight; more decompositions exist.
