Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522460, here are decompositions:

  • 19 + 31522441 = 31522460
  • 97 + 31522363 = 31522460
  • 103 + 31522357 = 31522460
  • 163 + 31522297 = 31522460
  • 241 + 31522219 = 31522460
  • 331 + 31522129 = 31522460
  • 439 + 31522021 = 31522460
  • 577 + 31521883 = 31522460

Showing the first eight; more decompositions exist.
