Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77656, here are decompositions:

  • 83 + 77573 = 77656
  • 107 + 77549 = 77656
  • 113 + 77543 = 77656
  • 167 + 77489 = 77656
  • 179 + 77477 = 77656
  • 239 + 77417 = 77656
  • 317 + 77339 = 77656
  • 389 + 77267 = 77656

Showing the first eight; more decompositions exist.
