Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 501280, here are decompositions:

23 + 501257 = 501280
47 + 501233 = 501280
71 + 501209 = 501280
83 + 501197 = 501280
89 + 501191 = 501280
107 + 501173 = 501280
149 + 501131 = 501280
191 + 501089 = 501280

Showing the first eight; more decompositions exist.
