Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 505620, here are decompositions:

7 + 505613 = 505620
13 + 505607 = 505620
19 + 505601 = 505620
47 + 505573 = 505620
61 + 505559 = 505620
83 + 505537 = 505620
97 + 505523 = 505620
107 + 505513 = 505620

Showing the first eight; more decompositions exist.
