Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31486924, here are decompositions:

  • 71 + 31486853 = 31486924
  • 173 + 31486751 = 31486924
  • 191 + 31486733 = 31486924
  • 197 + 31486727 = 31486924
  • 263 + 31486661 = 31486924
  • 281 + 31486643 = 31486924
  • 311 + 31486613 = 31486924
  • 353 + 31486571 = 31486924

Showing the first eight; more decompositions exist.
