Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534656, here are decompositions:

  • 5 + 31534651 = 31534656
  • 19 + 31534637 = 31534656
  • 59 + 31534597 = 31534656
  • 67 + 31534589 = 31534656
  • 103 + 31534553 = 31534656
  • 113 + 31534543 = 31534656
  • 163 + 31534493 = 31534656
  • 173 + 31534483 = 31534656

Showing the first eight; more decompositions exist.
