Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31530686, here are decompositions:

  • 3 + 31530683 = 31530686
  • 7 + 31530679 = 31530686
  • 37 + 31530649 = 31530686
  • 43 + 31530643 = 31530686
  • 79 + 31530607 = 31530686
  • 97 + 31530589 = 31530686
  • 163 + 31530523 = 31530686
  • 199 + 31530487 = 31530686

Showing the first eight; more decompositions exist.
