Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8639456, here are decompositions:

  • 3 + 8639453 = 8639456
  • 13 + 8639443 = 8639456
  • 43 + 8639413 = 8639456
  • 109 + 8639347 = 8639456
  • 157 + 8639299 = 8639456
  • 193 + 8639263 = 8639456
  • 229 + 8639227 = 8639456
  • 307 + 8639149 = 8639456

Showing the first eight; more decompositions exist.
