Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31485996, here are decompositions:

  • 23 + 31485973 = 31485996
  • 37 + 31485959 = 31485996
  • 43 + 31485953 = 31485996
  • 79 + 31485917 = 31485996
  • 103 + 31485893 = 31485996
  • 107 + 31485889 = 31485996
  • 163 + 31485833 = 31485996
  • 173 + 31485823 = 31485996

Showing the first eight; more decompositions exist.
