Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 505288, here are decompositions:

5 + 505283 = 505288
11 + 505277 = 505288
101 + 505187 = 505288
107 + 505181 = 505288
131 + 505157 = 505288
149 + 505139 = 505288
191 + 505097 = 505288
197 + 505091 = 505288

Showing the first eight; more decompositions exist.
