Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 505248, here are decompositions:

11 + 505237 = 505248
17 + 505231 = 505248
47 + 505201 = 505248
61 + 505187 = 505248
67 + 505181 = 505248
89 + 505159 = 505248
109 + 505139 = 505248
131 + 505117 = 505248

Showing the first eight; more decompositions exist.
