Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522624, here are decompositions:

  • 11 + 31522613 = 31522624
  • 41 + 31522583 = 31522624
  • 71 + 31522553 = 31522624
  • 83 + 31522541 = 31522624
  • 101 + 31522523 = 31522624
  • 131 + 31522493 = 31522624
  • 173 + 31522451 = 31522624
  • 191 + 31522433 = 31522624

Showing the first eight; more decompositions exist.
