Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31530788, here are decompositions:

  • 109 + 31530679 = 31530788
  • 127 + 31530661 = 31530788
  • 139 + 31530649 = 31530788
  • 151 + 31530637 = 31530788
  • 181 + 31530607 = 31530788
  • 199 + 31530589 = 31530788
  • 337 + 31530451 = 31530788
  • 379 + 31530409 = 31530788

Showing the first eight; more decompositions exist.
