Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31623250, here are decompositions:

  • 41 + 31623209 = 31623250
  • 83 + 31623167 = 31623250
  • 137 + 31623113 = 31623250
  • 227 + 31623023 = 31623250
  • 311 + 31622939 = 31623250
  • 317 + 31622933 = 31623250
  • 509 + 31622741 = 31623250
  • 521 + 31622729 = 31623250

Showing the first eight; more decompositions exist.
