Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31548656, here are decompositions:

  • 3 + 31548653 = 31548656
  • 37 + 31548619 = 31548656
  • 43 + 31548613 = 31548656
  • 79 + 31548577 = 31548656
  • 109 + 31548547 = 31548656
  • 157 + 31548499 = 31548656
  • 229 + 31548427 = 31548656
  • 313 + 31548343 = 31548656

Showing the first eight; more decompositions exist.
