Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533710, here are decompositions:

  • 3 + 31533707 = 31533710
  • 73 + 31533637 = 31533710
  • 79 + 31533631 = 31533710
  • 97 + 31533613 = 31533710
  • 139 + 31533571 = 31533710
  • 163 + 31533547 = 31533710
  • 193 + 31533517 = 31533710
  • 199 + 31533511 = 31533710

Showing the first eight; more decompositions exist.
