Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294987688, here are decompositions:

  • 7 + 4294987681 = 4294987688
  • 37 + 4294987651 = 4294987688
  • 67 + 4294987621 = 4294987688
  • 109 + 4294987579 = 4294987688
  • 127 + 4294987561 = 4294987688
  • 331 + 4294987357 = 4294987688
  • 457 + 4294987231 = 4294987688
  • 547 + 4294987141 = 4294987688

Showing the first eight; more decompositions exist.
