Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522824, here are decompositions:

  • 107 + 31522717 = 31522824
  • 131 + 31522693 = 31522824
  • 167 + 31522657 = 31522824
  • 191 + 31522633 = 31522824
  • 211 + 31522613 = 31522824
  • 227 + 31522597 = 31522824
  • 233 + 31522591 = 31522824
  • 241 + 31522583 = 31522824

Showing the first eight; more decompositions exist.
