Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459748, here are decompositions:

  • 31 + 31459717 = 31459748
  • 97 + 31459651 = 31459748
  • 127 + 31459621 = 31459748
  • 139 + 31459609 = 31459748
  • 349 + 31459399 = 31459748
  • 409 + 31459339 = 31459748
  • 457 + 31459291 = 31459748
  • 487 + 31459261 = 31459748

Showing the first eight; more decompositions exist.
