Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 521066, here are decompositions:

3 + 521063 = 521066
19 + 521047 = 521066
43 + 521023 = 521066
97 + 520969 = 521066
103 + 520963 = 521066
109 + 520957 = 521066
199 + 520867 = 521066
229 + 520837 = 521066

Showing the first eight; more decompositions exist.
