Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31512336, here are decompositions:

  • 5 + 31512331 = 31512336
  • 29 + 31512307 = 31512336
  • 47 + 31512289 = 31512336
  • 83 + 31512253 = 31512336
  • 127 + 31512209 = 31512336
  • 137 + 31512199 = 31512336
  • 223 + 31512113 = 31512336
  • 227 + 31512109 = 31512336

Showing the first eight; more decompositions exist.
