Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 505330, here are decompositions:

3 + 505327 = 505330
11 + 505319 = 505330
17 + 505313 = 505330
29 + 505301 = 505330
47 + 505283 = 505330
53 + 505277 = 505330
149 + 505181 = 505330
173 + 505157 = 505330

Showing the first eight; more decompositions exist.
