Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72286, here are decompositions:

  • 17 + 72269 = 72286
  • 59 + 72227 = 72286
  • 113 + 72173 = 72286
  • 197 + 72089 = 72286
  • 233 + 72053 = 72286
  • 239 + 72047 = 72286
  • 293 + 71993 = 72286
  • 353 + 71933 = 72286

Showing the first eight; more decompositions exist.
