Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19328, here are decompositions:

  • 19 + 19309 = 19328
  • 61 + 19267 = 19328
  • 79 + 19249 = 19328
  • 97 + 19231 = 19328
  • 109 + 19219 = 19328
  • 241 + 19087 = 19328
  • 277 + 19051 = 19328
  • 349 + 18979 = 19328

Showing the first eight; more decompositions exist.
