Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 528370, here are decompositions:

41 + 528329 = 528370
53 + 528317 = 528370
71 + 528299 = 528370
107 + 528263 = 528370
173 + 528197 = 528370
179 + 528191 = 528370
233 + 528137 = 528370
239 + 528131 = 528370

Showing the first eight; more decompositions exist.
