Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523122, here are decompositions:

  • 3 + 31523119 = 31523122
  • 11 + 31523111 = 31523122
  • 23 + 31523099 = 31523122
  • 41 + 31523081 = 31523122
  • 101 + 31523021 = 31523122
  • 233 + 31522889 = 31523122
  • 509 + 31522613 = 31523122
  • 569 + 31522553 = 31523122

Showing the first eight; more decompositions exist.
