Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294987664, here are decompositions:

  • 13 + 4294987651 = 4294987664
  • 43 + 4294987621 = 4294987664
  • 103 + 4294987561 = 4294987664
  • 271 + 4294987393 = 4294987664
  • 277 + 4294987387 = 4294987664
  • 307 + 4294987357 = 4294987664
  • 433 + 4294987231 = 4294987664
  • 523 + 4294987141 = 4294987664

Showing the first eight; more decompositions exist.
