Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8684720, here are decompositions:

  • 7 + 8684713 = 8684720
  • 199 + 8684521 = 8684720
  • 241 + 8684479 = 8684720
  • 283 + 8684437 = 8684720
  • 313 + 8684407 = 8684720
  • 379 + 8684341 = 8684720
  • 463 + 8684257 = 8684720
  • 547 + 8684173 = 8684720

Showing the first eight; more decompositions exist.
