Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294985720, here are decompositions:

  • 37 + 4294985683 = 4294985720
  • 73 + 4294985647 = 4294985720
  • 97 + 4294985623 = 4294985720
  • 139 + 4294985581 = 4294985720
  • 229 + 4294985491 = 4294985720
  • 271 + 4294985449 = 4294985720
  • 283 + 4294985437 = 4294985720
  • 409 + 4294985311 = 4294985720

Showing the first eight; more decompositions exist.
