Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 505392, here are decompositions:

23 + 505369 = 505392
53 + 505339 = 505392
71 + 505321 = 505392
73 + 505319 = 505392
79 + 505313 = 505392
109 + 505283 = 505392
113 + 505279 = 505392
179 + 505213 = 505392

Showing the first eight; more decompositions exist.
