Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 528226, here are decompositions:

3 + 528223 = 528226
29 + 528197 = 528226
59 + 528167 = 528226
89 + 528137 = 528226
173 + 528053 = 528226
233 + 527993 = 528226
239 + 527987 = 528226
317 + 527909 = 528226

Showing the first eight; more decompositions exist.
