Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 525256, here are decompositions:

3 + 525253 = 525256
47 + 525209 = 525256
89 + 525167 = 525256
113 + 525143 = 525256
227 + 525029 = 525256
239 + 525017 = 525256
257 + 524999 = 525256
293 + 524963 = 525256

Showing the first eight; more decompositions exist.
