Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525746, here are decompositions:

  • 23 + 31525723 = 31525746
  • 29 + 31525717 = 31525746
  • 47 + 31525699 = 31525746
  • 59 + 31525687 = 31525746
  • 89 + 31525657 = 31525746
  • 97 + 31525649 = 31525746
  • 137 + 31525609 = 31525746
  • 139 + 31525607 = 31525746

Showing the first eight; more decompositions exist.
