Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 521336, here are decompositions:

7 + 521329 = 521336
19 + 521317 = 521336
37 + 521299 = 521336
157 + 521179 = 521336
163 + 521173 = 521336
199 + 521137 = 521336
229 + 521107 = 521336
313 + 521023 = 521336

Showing the first eight; more decompositions exist.
