Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 525226, here are decompositions:

5 + 525221 = 525226
17 + 525209 = 525226
59 + 525167 = 525226
83 + 525143 = 525226
89 + 525137 = 525226
197 + 525029 = 525226
227 + 524999 = 525226
257 + 524969 = 525226

Showing the first eight; more decompositions exist.
