Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525710, here are decompositions:

  • 11 + 31525699 = 31525710
  • 23 + 31525687 = 31525710
  • 53 + 31525657 = 31525710
  • 59 + 31525651 = 31525710
  • 61 + 31525649 = 31525710
  • 101 + 31525609 = 31525710
  • 103 + 31525607 = 31525710
  • 107 + 31525603 = 31525710

Showing the first eight; more decompositions exist.
