Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545956, here are decompositions:

  • 3 + 31545953 = 31545956
  • 37 + 31545919 = 31545956
  • 97 + 31545859 = 31545956
  • 193 + 31545763 = 31545956
  • 349 + 31545607 = 31545956
  • 457 + 31545499 = 31545956
  • 487 + 31545469 = 31545956
  • 577 + 31545379 = 31545956

Showing the first eight; more decompositions exist.
