Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 505222, here are decompositions:

41 + 505181 = 505222
83 + 505139 = 505222
131 + 505091 = 505222
149 + 505073 = 505222
173 + 505049 = 505222
191 + 505031 = 505222
233 + 504989 = 505222
239 + 504983 = 505222

Showing the first eight; more decompositions exist.
