Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 522668, here are decompositions:

7 + 522661 = 522668
31 + 522637 = 522668
67 + 522601 = 522668
127 + 522541 = 522668
151 + 522517 = 522668
199 + 522469 = 522668
229 + 522439 = 522668
277 + 522391 = 522668

Showing the first eight; more decompositions exist.
