Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 501256, here are decompositions:

23 + 501233 = 501256
47 + 501209 = 501256
53 + 501203 = 501256
59 + 501197 = 501256
83 + 501173 = 501256
167 + 501089 = 501256
179 + 501077 = 501256
227 + 501029 = 501256

Showing the first eight; more decompositions exist.
