Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 500228, here are decompositions:

19 + 500209 = 500228
31 + 500197 = 500228
61 + 500167 = 500228
109 + 500119 = 500228
199 + 500029 = 500228
271 + 499957 = 500228
331 + 499897 = 500228
349 + 499879 = 500228

Showing the first eight; more decompositions exist.
