Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 505228, here are decompositions:

41 + 505187 = 505228
47 + 505181 = 505228
71 + 505157 = 505228
89 + 505139 = 505228
131 + 505097 = 505228
137 + 505091 = 505228
167 + 505061 = 505228
179 + 505049 = 505228

Showing the first eight; more decompositions exist.
