Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 521016, here are decompositions:

7 + 521009 = 521016
47 + 520969 = 521016
53 + 520963 = 521016
59 + 520957 = 521016
73 + 520943 = 521016
103 + 520913 = 521016
127 + 520889 = 521016
149 + 520867 = 521016

Showing the first eight; more decompositions exist.
