Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31548328, here are decompositions:

  • 5 + 31548323 = 31548328
  • 29 + 31548299 = 31548328
  • 41 + 31548287 = 31548328
  • 47 + 31548281 = 31548328
  • 59 + 31548269 = 31548328
  • 179 + 31548149 = 31548328
  • 281 + 31548047 = 31548328
  • 311 + 31548017 = 31548328

Showing the first eight; more decompositions exist.
