Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544636, here are decompositions:

  • 103 + 31544533 = 31544636
  • 127 + 31544509 = 31544636
  • 313 + 31544323 = 31544636
  • 457 + 31544179 = 31544636
  • 547 + 31544089 = 31544636
  • 709 + 31543927 = 31544636
  • 733 + 31543903 = 31544636
  • 853 + 31543783 = 31544636

Showing the first eight; more decompositions exist.
