Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31550712, here are decompositions:

  • 13 + 31550699 = 31550712
  • 31 + 31550681 = 31550712
  • 41 + 31550671 = 31550712
  • 101 + 31550611 = 31550712
  • 113 + 31550599 = 31550712
  • 131 + 31550581 = 31550712
  • 139 + 31550573 = 31550712
  • 173 + 31550539 = 31550712

Showing the first eight; more decompositions exist.
