Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8649492, here are decompositions:

  • 13 + 8649479 = 8649492
  • 23 + 8649469 = 8649492
  • 29 + 8649463 = 8649492
  • 41 + 8649451 = 8649492
  • 73 + 8649419 = 8649492
  • 83 + 8649409 = 8649492
  • 101 + 8649391 = 8649492
  • 109 + 8649383 = 8649492

Showing the first eight; more decompositions exist.
