Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 522256, here are decompositions:

5 + 522251 = 522256
17 + 522239 = 522256
23 + 522233 = 522256
29 + 522227 = 522256
89 + 522167 = 522256
173 + 522083 = 522256
197 + 522059 = 522256
239 + 522017 = 522256

Showing the first eight; more decompositions exist.
