Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8620340, here are decompositions:

  • 13 + 8620327 = 8620340
  • 73 + 8620267 = 8620340
  • 109 + 8620231 = 8620340
  • 151 + 8620189 = 8620340
  • 181 + 8620159 = 8620340
  • 199 + 8620141 = 8620340
  • 229 + 8620111 = 8620340
  • 271 + 8620069 = 8620340

Showing the first eight; more decompositions exist.
