Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 505290, here are decompositions:

7 + 505283 = 505290
11 + 505279 = 505290
13 + 505277 = 505290
53 + 505237 = 505290
59 + 505231 = 505290
89 + 505201 = 505290
103 + 505187 = 505290
109 + 505181 = 505290

Showing the first eight; more decompositions exist.
