Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8647480, here are decompositions:

  • 11 + 8647469 = 8647480
  • 71 + 8647409 = 8647480
  • 89 + 8647391 = 8647480
  • 113 + 8647367 = 8647480
  • 131 + 8647349 = 8647480
  • 227 + 8647253 = 8647480
  • 251 + 8647229 = 8647480
  • 353 + 8647127 = 8647480

Showing the first eight; more decompositions exist.
