Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544814, here are decompositions:

  • 31 + 31544783 = 31544814
  • 43 + 31544771 = 31544814
  • 97 + 31544717 = 31544814
  • 101 + 31544713 = 31544814
  • 157 + 31544657 = 31544814
  • 227 + 31544587 = 31544814
  • 241 + 31544573 = 31544814
  • 263 + 31544551 = 31544814

Showing the first eight; more decompositions exist.
