Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 521082, here are decompositions:

19 + 521063 = 521082
31 + 521051 = 521082
41 + 521041 = 521082
43 + 521039 = 521082
59 + 521023 = 521082
61 + 521021 = 521082
73 + 521009 = 521082
101 + 520981 = 521082

Showing the first eight; more decompositions exist.
