Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31546660, here are decompositions:

  • 3 + 31546657 = 31546660
  • 23 + 31546637 = 31546660
  • 59 + 31546601 = 31546660
  • 107 + 31546553 = 31546660
  • 191 + 31546469 = 31546660
  • 239 + 31546421 = 31546660
  • 311 + 31546349 = 31546660
  • 359 + 31546301 = 31546660

Showing the first eight; more decompositions exist.
