Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8698640, here are decompositions:

  • 7 + 8698633 = 8698640
  • 19 + 8698621 = 8698640
  • 37 + 8698603 = 8698640
  • 43 + 8698597 = 8698640
  • 241 + 8698399 = 8698640
  • 271 + 8698369 = 8698640
  • 277 + 8698363 = 8698640
  • 487 + 8698153 = 8698640

Showing the first eight; more decompositions exist.
