Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77668, here are decompositions:

  • 47 + 77621 = 77668
  • 179 + 77489 = 77668
  • 191 + 77477 = 77668
  • 197 + 77471 = 77668
  • 251 + 77417 = 77668
  • 317 + 77351 = 77668
  • 389 + 77279 = 77668
  • 401 + 77267 = 77668

Showing the first eight; more decompositions exist.
