Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 525288, here are decompositions:

31 + 525257 = 525288
41 + 525247 = 525288
47 + 525241 = 525288
67 + 525221 = 525288
79 + 525209 = 525288
89 + 525199 = 525288
97 + 525191 = 525288
131 + 525157 = 525288

Showing the first eight; more decompositions exist.
