Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 505298, here are decompositions:

19 + 505279 = 505298
61 + 505237 = 505298
67 + 505231 = 505298
97 + 505201 = 505298
139 + 505159 = 505298
181 + 505117 = 505298
271 + 505027 = 505298
307 + 504991 = 505298

Showing the first eight; more decompositions exist.
