Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8646340, here are decompositions:

  • 11 + 8646329 = 8646340
  • 23 + 8646317 = 8646340
  • 41 + 8646299 = 8646340
  • 47 + 8646293 = 8646340
  • 71 + 8646269 = 8646340
  • 83 + 8646257 = 8646340
  • 107 + 8646233 = 8646340
  • 113 + 8646227 = 8646340

Showing the first eight; more decompositions exist.
