Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 522218, here are decompositions:

7 + 522211 = 522218
19 + 522199 = 522218
61 + 522157 = 522218
139 + 522079 = 522218
157 + 522061 = 522218
181 + 522037 = 522218
331 + 521887 = 522218
337 + 521881 = 522218

Showing the first eight; more decompositions exist.
