Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31497510, here are decompositions:

  • 19 + 31497491 = 31497510
  • 41 + 31497469 = 31497510
  • 43 + 31497467 = 31497510
  • 47 + 31497463 = 31497510
  • 61 + 31497449 = 31497510
  • 67 + 31497443 = 31497510
  • 101 + 31497409 = 31497510
  • 151 + 31497359 = 31497510

Showing the first eight; more decompositions exist.
