Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 501220, here are decompositions:

3 + 501217 = 501220
11 + 501209 = 501220
17 + 501203 = 501220
23 + 501197 = 501220
29 + 501191 = 501220
47 + 501173 = 501220
89 + 501131 = 501220
131 + 501089 = 501220

Showing the first eight; more decompositions exist.
