Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533650, here are decompositions:

  • 13 + 31533637 = 31533650
  • 19 + 31533631 = 31533650
  • 37 + 31533613 = 31533650
  • 79 + 31533571 = 31533650
  • 103 + 31533547 = 31533650
  • 139 + 31533511 = 31533650
  • 151 + 31533499 = 31533650
  • 199 + 31533451 = 31533650

Showing the first eight; more decompositions exist.
