Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 525388, here are decompositions:

11 + 525377 = 525388
29 + 525359 = 525388
89 + 525299 = 525388
131 + 525257 = 525388
167 + 525221 = 525388
179 + 525209 = 525388
197 + 525191 = 525388
251 + 525137 = 525388

Showing the first eight; more decompositions exist.
