Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 521330, here are decompositions:

13 + 521317 = 521330
31 + 521299 = 521330
79 + 521251 = 521330
151 + 521179 = 521330
157 + 521173 = 521330
163 + 521167 = 521330
193 + 521137 = 521330
211 + 521119 = 521330

Showing the first eight; more decompositions exist.
