Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 505216, here are decompositions:

3 + 505213 = 505216
29 + 505187 = 505216
59 + 505157 = 505216
149 + 505067 = 505216
167 + 505049 = 505216
227 + 504989 = 505216
233 + 504983 = 505216
263 + 504953 = 505216

Showing the first eight; more decompositions exist.
