Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 525258, here are decompositions:

5 + 525253 = 525258
11 + 525247 = 525258
17 + 525241 = 525258
37 + 525221 = 525258
59 + 525199 = 525258
67 + 525191 = 525258
101 + 525157 = 525258
131 + 525127 = 525258

Showing the first eight; more decompositions exist.
