Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 521822, here are decompositions:

3 + 521819 = 521822
13 + 521809 = 521822
31 + 521791 = 521822
73 + 521749 = 521822
79 + 521743 = 521822
151 + 521671 = 521822
163 + 521659 = 521822
181 + 521641 = 521822

Showing the first eight; more decompositions exist.
