Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 521590, here are decompositions:

23 + 521567 = 521590
53 + 521537 = 521590
71 + 521519 = 521590
107 + 521483 = 521590
191 + 521399 = 521590
197 + 521393 = 521590
227 + 521363 = 521590
233 + 521357 = 521590

Showing the first eight; more decompositions exist.
