Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 525238, here are decompositions:

17 + 525221 = 525238
29 + 525209 = 525238
47 + 525191 = 525238
71 + 525167 = 525238
101 + 525137 = 525238
137 + 525101 = 525238
239 + 524999 = 525238
257 + 524981 = 525238

Showing the first eight; more decompositions exist.
