Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 521198, here are decompositions:

19 + 521179 = 521198
31 + 521167 = 521198
37 + 521161 = 521198
61 + 521137 = 521198
79 + 521119 = 521198
151 + 521047 = 521198
157 + 521041 = 521198
229 + 520969 = 521198

Showing the first eight; more decompositions exist.
