Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 521074, here are decompositions:

11 + 521063 = 521074
23 + 521051 = 521074
53 + 521021 = 521074
107 + 520967 = 521074
131 + 520943 = 521074
233 + 520841 = 521074
311 + 520763 = 521074
353 + 520721 = 521074

Showing the first eight; more decompositions exist.
