Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544668, here are decompositions:

  • 11 + 31544657 = 31544668
  • 107 + 31544561 = 31544668
  • 137 + 31544531 = 31544668
  • 251 + 31544417 = 31544668
  • 461 + 31544207 = 31544668
  • 479 + 31544189 = 31544668
  • 569 + 31544099 = 31544668
  • 647 + 31544021 = 31544668

Showing the first eight; more decompositions exist.
