Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8641464, here are decompositions:

  • 11 + 8641453 = 8641464
  • 31 + 8641433 = 8641464
  • 43 + 8641421 = 8641464
  • 103 + 8641361 = 8641464
  • 113 + 8641351 = 8641464
  • 137 + 8641327 = 8641464
  • 163 + 8641301 = 8641464
  • 191 + 8641273 = 8641464

Showing the first eight; more decompositions exist.
