Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8644470, here are decompositions:

  • 13 + 8644457 = 8644470
  • 17 + 8644453 = 8644470
  • 19 + 8644451 = 8644470
  • 31 + 8644439 = 8644470
  • 73 + 8644397 = 8644470
  • 139 + 8644331 = 8644470
  • 227 + 8644243 = 8644470
  • 239 + 8644231 = 8644470

Showing the first eight; more decompositions exist.
