Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31508616, here are decompositions:

  • 37 + 31508579 = 31508616
  • 47 + 31508569 = 31508616
  • 59 + 31508557 = 31508616
  • 67 + 31508549 = 31508616
  • 89 + 31508527 = 31508616
  • 107 + 31508509 = 31508616
  • 109 + 31508507 = 31508616
  • 163 + 31508453 = 31508616

Showing the first eight; more decompositions exist.
