Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294991440, here are decompositions:

  • 11 + 4294991429 = 4294991440
  • 17 + 4294991423 = 4294991440
  • 23 + 4294991417 = 4294991440
  • 41 + 4294991399 = 4294991440
  • 53 + 4294991387 = 4294991440
  • 83 + 4294991357 = 4294991440
  • 587 + 4294990853 = 4294991440
  • 653 + 4294990787 = 4294991440

Showing the first eight; more decompositions exist.
