Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 521608, here are decompositions:

5 + 521603 = 521608
41 + 521567 = 521608
71 + 521537 = 521608
89 + 521519 = 521608
137 + 521471 = 521608
179 + 521429 = 521608
239 + 521369 = 521608
251 + 521357 = 521608

Showing the first eight; more decompositions exist.
