Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534386, here are decompositions:

  • 17 + 31534369 = 31534386
  • 43 + 31534343 = 31534386
  • 53 + 31534333 = 31534386
  • 89 + 31534297 = 31534386
  • 139 + 31534247 = 31534386
  • 199 + 31534187 = 31534386
  • 269 + 31534117 = 31534386
  • 283 + 31534103 = 31534386

Showing the first eight; more decompositions exist.
