Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545374, here are decompositions:

  • 31 + 31545343 = 31545374
  • 43 + 31545331 = 31545374
  • 163 + 31545211 = 31545374
  • 193 + 31545181 = 31545374
  • 277 + 31545097 = 31545374
  • 283 + 31545091 = 31545374
  • 307 + 31545067 = 31545374
  • 313 + 31545061 = 31545374

Showing the first eight; more decompositions exist.
