Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31623950, here are decompositions:

  • 3 + 31623947 = 31623950
  • 19 + 31623931 = 31623950
  • 229 + 31623721 = 31623950
  • 283 + 31623667 = 31623950
  • 439 + 31623511 = 31623950
  • 577 + 31623373 = 31623950
  • 607 + 31623343 = 31623950
  • 613 + 31623337 = 31623950

Showing the first eight; more decompositions exist.
