Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526666, here are decompositions:

  • 19 + 31526647 = 31526666
  • 103 + 31526563 = 31526666
  • 139 + 31526527 = 31526666
  • 163 + 31526503 = 31526666
  • 277 + 31526389 = 31526666
  • 307 + 31526359 = 31526666
  • 349 + 31526317 = 31526666
  • 439 + 31526227 = 31526666

Showing the first eight; more decompositions exist.
