Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 501290, here are decompositions:

3 + 501287 = 501290
19 + 501271 = 501290
61 + 501229 = 501290
67 + 501223 = 501290
73 + 501217 = 501290
103 + 501187 = 501290
151 + 501139 = 501290
157 + 501133 = 501290

Showing the first eight; more decompositions exist.
