Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31546870, here are decompositions:

  • 23 + 31546847 = 31546870
  • 53 + 31546817 = 31546870
  • 71 + 31546799 = 31546870
  • 149 + 31546721 = 31546870
  • 233 + 31546637 = 31546870
  • 269 + 31546601 = 31546870
  • 317 + 31546553 = 31546870
  • 401 + 31546469 = 31546870

Showing the first eight; more decompositions exist.
