Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 521982, here are decompositions:

53 + 521929 = 521982
59 + 521923 = 521982
79 + 521903 = 521982
101 + 521881 = 521982
103 + 521879 = 521982
113 + 521869 = 521982
151 + 521831 = 521982
163 + 521819 = 521982

Showing the first eight; more decompositions exist.
