Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545636, here are decompositions:

  • 7 + 31545629 = 31545636
  • 13 + 31545623 = 31545636
  • 29 + 31545607 = 31545636
  • 37 + 31545599 = 31545636
  • 137 + 31545499 = 31545636
  • 149 + 31545487 = 31545636
  • 167 + 31545469 = 31545636
  • 197 + 31545439 = 31545636

Showing the first eight; more decompositions exist.
