Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544672, here are decompositions:

  • 139 + 31544533 = 31544672
  • 163 + 31544509 = 31544672
  • 349 + 31544323 = 31544672
  • 541 + 31544131 = 31544672
  • 619 + 31544053 = 31544672
  • 631 + 31544041 = 31544672
  • 661 + 31544011 = 31544672
  • 769 + 31543903 = 31544672

Showing the first eight; more decompositions exist.
