Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8602640, here are decompositions:

  • 3 + 8602637 = 8602640
  • 73 + 8602567 = 8602640
  • 97 + 8602543 = 8602640
  • 223 + 8602417 = 8602640
  • 337 + 8602303 = 8602640
  • 367 + 8602273 = 8602640
  • 421 + 8602219 = 8602640
  • 439 + 8602201 = 8602640

Showing the first eight; more decompositions exist.
