Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31546668, here are decompositions:

  • 5 + 31546663 = 31546668
  • 7 + 31546661 = 31546668
  • 11 + 31546657 = 31546668
  • 31 + 31546637 = 31546668
  • 47 + 31546621 = 31546668
  • 67 + 31546601 = 31546668
  • 71 + 31546597 = 31546668
  • 199 + 31546469 = 31546668

Showing the first eight; more decompositions exist.
