Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 521130, here are decompositions:

11 + 521119 = 521130
23 + 521107 = 521130
67 + 521063 = 521130
79 + 521051 = 521130
83 + 521047 = 521130
89 + 521041 = 521130
107 + 521023 = 521130
109 + 521021 = 521130

Showing the first eight; more decompositions exist.
