Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525862, here are decompositions:

  • 13 + 31525849 = 31525862
  • 79 + 31525783 = 31525862
  • 139 + 31525723 = 31525862
  • 163 + 31525699 = 31525862
  • 211 + 31525651 = 31525862
  • 373 + 31525489 = 31525862
  • 601 + 31525261 = 31525862
  • 619 + 31525243 = 31525862

Showing the first eight; more decompositions exist.
