Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 505522, here are decompositions:

11 + 505511 = 505522
29 + 505493 = 505522
41 + 505481 = 505522
53 + 505469 = 505522
113 + 505409 = 505522
239 + 505283 = 505522
383 + 505139 = 505522
431 + 505091 = 505522

Showing the first eight; more decompositions exist.
