Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 525318, here are decompositions:

5 + 525313 = 525318
19 + 525299 = 525318
61 + 525257 = 525318
71 + 525247 = 525318
97 + 525221 = 525318
109 + 525209 = 525318
127 + 525191 = 525318
151 + 525167 = 525318

Showing the first eight; more decompositions exist.
