Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545708, here are decompositions:

  • 41 + 31545667 = 31545708
  • 67 + 31545641 = 31545708
  • 79 + 31545629 = 31545708
  • 97 + 31545611 = 31545708
  • 101 + 31545607 = 31545708
  • 109 + 31545599 = 31545708
  • 239 + 31545469 = 31545708
  • 269 + 31545439 = 31545708

Showing the first eight; more decompositions exist.
