Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613672, here are decompositions:

  • 3 + 31613669 = 31613672
  • 43 + 31613629 = 31613672
  • 271 + 31613401 = 31613672
  • 331 + 31613341 = 31613672
  • 619 + 31613053 = 31613672
  • 691 + 31612981 = 31613672
  • 733 + 31612939 = 31613672
  • 919 + 31612753 = 31613672

Showing the first eight; more decompositions exist.
