Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 521026, here are decompositions:

3 + 521023 = 521026
5 + 521021 = 521026
17 + 521009 = 521026
59 + 520967 = 521026
83 + 520943 = 521026
113 + 520913 = 521026
137 + 520889 = 521026
173 + 520853 = 521026

Showing the first eight; more decompositions exist.
