Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31625796, here are decompositions:

  • 17 + 31625779 = 31625796
  • 19 + 31625777 = 31625796
  • 23 + 31625773 = 31625796
  • 29 + 31625767 = 31625796
  • 43 + 31625753 = 31625796
  • 73 + 31625723 = 31625796
  • 149 + 31625647 = 31625796
  • 179 + 31625617 = 31625796

Showing the first eight; more decompositions exist.
