Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31486914, here are decompositions:

  • 61 + 31486853 = 31486914
  • 163 + 31486751 = 31486914
  • 181 + 31486733 = 31486914
  • 191 + 31486723 = 31486914
  • 257 + 31486657 = 31486914
  • 271 + 31486643 = 31486914
  • 281 + 31486633 = 31486914
  • 311 + 31486603 = 31486914

Showing the first eight; more decompositions exist.
