Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617516, here are decompositions:

  • 13 + 31617503 = 31617516
  • 19 + 31617497 = 31617516
  • 23 + 31617493 = 31617516
  • 59 + 31617457 = 31617516
  • 67 + 31617449 = 31617516
  • 103 + 31617413 = 31617516
  • 107 + 31617409 = 31617516
  • 109 + 31617407 = 31617516

Showing the first eight; more decompositions exist.
