Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8718128, here are decompositions:

  • 19 + 8718109 = 8718128
  • 31 + 8718097 = 8718128
  • 37 + 8718091 = 8718128
  • 271 + 8717857 = 8718128
  • 337 + 8717791 = 8718128
  • 379 + 8717749 = 8718128
  • 439 + 8717689 = 8718128
  • 571 + 8717557 = 8718128

Showing the first eight; more decompositions exist.
