Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31539762, here are decompositions:

  • 5 + 31539757 = 31539762
  • 101 + 31539661 = 31539762
  • 103 + 31539659 = 31539762
  • 113 + 31539649 = 31539762
  • 179 + 31539583 = 31539762
  • 193 + 31539569 = 31539762
  • 239 + 31539523 = 31539762
  • 263 + 31539499 = 31539762

Showing the first eight; more decompositions exist.
