Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 521068, here are decompositions:

5 + 521063 = 521068
17 + 521051 = 521068
29 + 521039 = 521068
47 + 521021 = 521068
59 + 521009 = 521068
101 + 520967 = 521068
179 + 520889 = 521068
227 + 520841 = 521068

Showing the first eight; more decompositions exist.
