Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522152, here are decompositions:

  • 23 + 31522129 = 31522152
  • 61 + 31522091 = 31522152
  • 131 + 31522021 = 31522152
  • 139 + 31522013 = 31522152
  • 173 + 31521979 = 31522152
  • 199 + 31521953 = 31522152
  • 269 + 31521883 = 31522152
  • 359 + 31521793 = 31522152

Showing the first eight; more decompositions exist.
