Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612896, here are decompositions:

  • 5 + 31612891 = 31612896
  • 23 + 31612873 = 31612896
  • 43 + 31612853 = 31612896
  • 137 + 31612759 = 31612896
  • 149 + 31612747 = 31612896
  • 157 + 31612739 = 31612896
  • 163 + 31612733 = 31612896
  • 167 + 31612729 = 31612896

Showing the first eight; more decompositions exist.
