Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617470, here are decompositions:

  • 13 + 31617457 = 31617470
  • 61 + 31617409 = 31617470
  • 67 + 31617403 = 31617470
  • 97 + 31617373 = 31617470
  • 109 + 31617361 = 31617470
  • 271 + 31617199 = 31617470
  • 337 + 31617133 = 31617470
  • 397 + 31617073 = 31617470

Showing the first eight; more decompositions exist.
