Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8672256, here are decompositions:

  • 17 + 8672239 = 8672256
  • 53 + 8672203 = 8672256
  • 79 + 8672177 = 8672256
  • 139 + 8672117 = 8672256
  • 157 + 8672099 = 8672256
  • 193 + 8672063 = 8672256
  • 269 + 8671987 = 8672256
  • 277 + 8671979 = 8672256

Showing the first eight; more decompositions exist.
