Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545536, here are decompositions:

  • 37 + 31545499 = 31545536
  • 67 + 31545469 = 31545536
  • 97 + 31545439 = 31545536
  • 157 + 31545379 = 31545536
  • 163 + 31545373 = 31545536
  • 193 + 31545343 = 31545536
  • 439 + 31545097 = 31545536
  • 487 + 31545049 = 31545536

Showing the first eight; more decompositions exist.
