Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526718, here are decompositions:

  • 5 + 31526713 = 31526718
  • 29 + 31526689 = 31526718
  • 71 + 31526647 = 31526718
  • 101 + 31526617 = 31526718
  • 191 + 31526527 = 31526718
  • 229 + 31526489 = 31526718
  • 241 + 31526477 = 31526718
  • 331 + 31526387 = 31526718

Showing the first eight; more decompositions exist.
