Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 522290, here are decompositions:

7 + 522283 = 522290
31 + 522259 = 522290
61 + 522229 = 522290
79 + 522211 = 522290
163 + 522127 = 522290
211 + 522079 = 522290
229 + 522061 = 522290
367 + 521923 = 522290

Showing the first eight; more decompositions exist.
