Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 501288, here are decompositions:

17 + 501271 = 501288
31 + 501257 = 501288
59 + 501229 = 501288
71 + 501217 = 501288
79 + 501209 = 501288
97 + 501191 = 501288
101 + 501187 = 501288
131 + 501157 = 501288

Showing the first eight; more decompositions exist.
