Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31512734, here are decompositions:

  • 3 + 31512731 = 31512734
  • 31 + 31512703 = 31512734
  • 61 + 31512673 = 31512734
  • 103 + 31512631 = 31512734
  • 283 + 31512451 = 31512734
  • 523 + 31512211 = 31512734
  • 613 + 31512121 = 31512734
  • 853 + 31511881 = 31512734

Showing the first eight; more decompositions exist.
