Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8638590, here are decompositions:

  • 7 + 8638583 = 8638590
  • 47 + 8638543 = 8638590
  • 73 + 8638517 = 8638590
  • 109 + 8638481 = 8638590
  • 113 + 8638477 = 8638590
  • 127 + 8638463 = 8638590
  • 137 + 8638453 = 8638590
  • 139 + 8638451 = 8638590

Showing the first eight; more decompositions exist.
