Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31549050, here are decompositions:

  • 7 + 31549043 = 31549050
  • 11 + 31549039 = 31549050
  • 31 + 31549019 = 31549050
  • 41 + 31549009 = 31549050
  • 53 + 31548997 = 31549050
  • 67 + 31548983 = 31549050
  • 89 + 31548961 = 31549050
  • 97 + 31548953 = 31549050

Showing the first eight; more decompositions exist.
