Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31623582, here are decompositions:

  • 59 + 31623523 = 31623582
  • 61 + 31623521 = 31623582
  • 71 + 31623511 = 31623582
  • 73 + 31623509 = 31623582
  • 83 + 31623499 = 31623582
  • 101 + 31623481 = 31623582
  • 103 + 31623479 = 31623582
  • 139 + 31623443 = 31623582

Showing the first eight; more decompositions exist.
