Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 521038, here are decompositions:

17 + 521021 = 521038
29 + 521009 = 521038
71 + 520967 = 521038
149 + 520889 = 521038
197 + 520841 = 521038
251 + 520787 = 521038
317 + 520721 = 521038
347 + 520691 = 521038

Showing the first eight; more decompositions exist.
