Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 500198, here are decompositions:

19 + 500179 = 500198
31 + 500167 = 500198
79 + 500119 = 500198
157 + 500041 = 500198
229 + 499969 = 500198
241 + 499957 = 500198
271 + 499927 = 500198
379 + 499819 = 500198

Showing the first eight; more decompositions exist.
