Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617564, here are decompositions:

  • 5 + 31617559 = 31617564
  • 31 + 31617533 = 31617564
  • 61 + 31617503 = 31617564
  • 67 + 31617497 = 31617564
  • 71 + 31617493 = 31617564
  • 103 + 31617461 = 31617564
  • 107 + 31617457 = 31617564
  • 151 + 31617413 = 31617564

Showing the first eight; more decompositions exist.
