Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31559110, here are decompositions:

  • 17 + 31559093 = 31559110
  • 29 + 31559081 = 31559110
  • 41 + 31559069 = 31559110
  • 59 + 31559051 = 31559110
  • 83 + 31559027 = 31559110
  • 113 + 31558997 = 31559110
  • 137 + 31558973 = 31559110
  • 227 + 31558883 = 31559110

Showing the first eight; more decompositions exist.
