Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31517302, here are decompositions:

  • 29 + 31517273 = 31517302
  • 59 + 31517243 = 31517302
  • 71 + 31517231 = 31517302
  • 239 + 31517063 = 31517302
  • 263 + 31517039 = 31517302
  • 281 + 31517021 = 31517302
  • 461 + 31516841 = 31517302
  • 491 + 31516811 = 31517302

Showing the first eight; more decompositions exist.
