Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542866, here are decompositions:

  • 37 + 31542829 = 31542866
  • 67 + 31542799 = 31542866
  • 79 + 31542787 = 31542866
  • 139 + 31542727 = 31542866
  • 163 + 31542703 = 31542866
  • 307 + 31542559 = 31542866
  • 379 + 31542487 = 31542866
  • 409 + 31542457 = 31542866

Showing the first eight; more decompositions exist.
