Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 521124, here are decompositions:

5 + 521119 = 521124
17 + 521107 = 521124
61 + 521063 = 521124
73 + 521051 = 521124
83 + 521041 = 521124
101 + 521023 = 521124
103 + 521021 = 521124
157 + 520967 = 521124

Showing the first eight; more decompositions exist.
