Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12536, here are decompositions:

  • 19 + 12517 = 12536
  • 79 + 12457 = 12536
  • 103 + 12433 = 12536
  • 127 + 12409 = 12536
  • 157 + 12379 = 12536
  • 163 + 12373 = 12536
  • 193 + 12343 = 12536
  • 283 + 12253 = 12536

Showing the first eight; more decompositions exist.
