Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545926, here are decompositions:

  • 3 + 31545923 = 31545926
  • 7 + 31545919 = 31545926
  • 67 + 31545859 = 31545926
  • 163 + 31545763 = 31545926
  • 439 + 31545487 = 31545926
  • 457 + 31545469 = 31545926
  • 487 + 31545439 = 31545926
  • 547 + 31545379 = 31545926

Showing the first eight; more decompositions exist.
