Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 505208, here are decompositions:

7 + 505201 = 505208
79 + 505129 = 505208
97 + 505111 = 505208
157 + 505051 = 505208
181 + 505027 = 505208
241 + 504967 = 505208
271 + 504937 = 505208
307 + 504901 = 505208

Showing the first eight; more decompositions exist.
