Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545528, here are decompositions:

  • 29 + 31545499 = 31545528
  • 41 + 31545487 = 31545528
  • 59 + 31545469 = 31545528
  • 89 + 31545439 = 31545528
  • 127 + 31545401 = 31545528
  • 137 + 31545391 = 31545528
  • 149 + 31545379 = 31545528
  • 197 + 31545331 = 31545528

Showing the first eight; more decompositions exist.
