Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525708, here are decompositions:

  • 59 + 31525649 = 31525708
  • 101 + 31525607 = 31525708
  • 107 + 31525601 = 31525708
  • 311 + 31525397 = 31525708
  • 419 + 31525289 = 31525708
  • 479 + 31525229 = 31525708
  • 587 + 31525121 = 31525708
  • 677 + 31525031 = 31525708

Showing the first eight; more decompositions exist.
