Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8647458, here are decompositions:

  • 11 + 8647447 = 8647458
  • 41 + 8647417 = 8647458
  • 47 + 8647411 = 8647458
  • 67 + 8647391 = 8647458
  • 89 + 8647369 = 8647458
  • 109 + 8647349 = 8647458
  • 181 + 8647277 = 8647458
  • 227 + 8647231 = 8647458

Showing the first eight; more decompositions exist.
