Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545662, here are decompositions:

  • 163 + 31545499 = 31545662
  • 193 + 31545469 = 31545662
  • 223 + 31545439 = 31545662
  • 271 + 31545391 = 31545662
  • 283 + 31545379 = 31545662
  • 331 + 31545331 = 31545662
  • 571 + 31545091 = 31545662
  • 601 + 31545061 = 31545662

Showing the first eight; more decompositions exist.
