Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534660, here are decompositions:

  • 23 + 31534637 = 31534660
  • 29 + 31534631 = 31534660
  • 71 + 31534589 = 31534660
  • 107 + 31534553 = 31534660
  • 167 + 31534493 = 31534660
  • 173 + 31534487 = 31534660
  • 233 + 31534427 = 31534660
  • 317 + 31534343 = 31534660

Showing the first eight; more decompositions exist.
