Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31485804, here are decompositions:

  • 5 + 31485799 = 31485804
  • 13 + 31485791 = 31485804
  • 37 + 31485767 = 31485804
  • 47 + 31485757 = 31485804
  • 61 + 31485743 = 31485804
  • 67 + 31485737 = 31485804
  • 83 + 31485721 = 31485804
  • 151 + 31485653 = 31485804

Showing the first eight; more decompositions exist.
