Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 525356, here are decompositions:

3 + 525353 = 525356
43 + 525313 = 525356
103 + 525253 = 525356
109 + 525247 = 525356
157 + 525199 = 525356
163 + 525193 = 525356
193 + 525163 = 525356
199 + 525157 = 525356

Showing the first eight; more decompositions exist.
