Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 525312, here are decompositions:

13 + 525299 = 525312
59 + 525253 = 525312
71 + 525241 = 525312
103 + 525209 = 525312
113 + 525199 = 525312
149 + 525163 = 525312
211 + 525101 = 525312
269 + 525043 = 525312

Showing the first eight; more decompositions exist.
