Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294987520, here are decompositions:

  • 127 + 4294987393 = 4294987520
  • 163 + 4294987357 = 4294987520
  • 379 + 4294987141 = 4294987520
  • 409 + 4294987111 = 4294987520
  • 463 + 4294987057 = 4294987520
  • 613 + 4294986907 = 4294987520
  • 631 + 4294986889 = 4294987520
  • 727 + 4294986793 = 4294987520

Showing the first eight; more decompositions exist.
