Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 521708, here are decompositions:

37 + 521671 = 521708
67 + 521641 = 521708
127 + 521581 = 521708
151 + 521557 = 521708
157 + 521551 = 521708
181 + 521527 = 521708
211 + 521497 = 521708
307 + 521401 = 521708

Showing the first eight; more decompositions exist.
