Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 505630, here are decompositions:

11 + 505619 = 505630
17 + 505613 = 505630
23 + 505607 = 505630
29 + 505601 = 505630
71 + 505559 = 505630
107 + 505523 = 505630
137 + 505493 = 505630
149 + 505481 = 505630

Showing the first eight; more decompositions exist.
