Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 505380, here are decompositions:

11 + 505369 = 505380
13 + 505367 = 505380
23 + 505357 = 505380
41 + 505339 = 505380
53 + 505327 = 505380
59 + 505321 = 505380
61 + 505319 = 505380
67 + 505313 = 505380

Showing the first eight; more decompositions exist.
