Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8759440, here are decompositions:

  • 17 + 8759423 = 8759440
  • 47 + 8759393 = 8759440
  • 83 + 8759357 = 8759440
  • 89 + 8759351 = 8759440
  • 101 + 8759339 = 8759440
  • 113 + 8759327 = 8759440
  • 167 + 8759273 = 8759440
  • 233 + 8759207 = 8759440

Showing the first eight; more decompositions exist.
