Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31538796, here are decompositions:

  • 7 + 31538789 = 31538796
  • 17 + 31538779 = 31538796
  • 43 + 31538753 = 31538796
  • 53 + 31538743 = 31538796
  • 67 + 31538729 = 31538796
  • 83 + 31538713 = 31538796
  • 103 + 31538693 = 31538796
  • 167 + 31538629 = 31538796

Showing the first eight; more decompositions exist.
