Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31546386, here are decompositions:

  • 17 + 31546369 = 31546386
  • 37 + 31546349 = 31546386
  • 83 + 31546303 = 31546386
  • 103 + 31546283 = 31546386
  • 107 + 31546279 = 31546386
  • 199 + 31546187 = 31546386
  • 227 + 31546159 = 31546386
  • 233 + 31546153 = 31546386

Showing the first eight; more decompositions exist.
