Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 501618, here are decompositions:

17 + 501601 = 501618
41 + 501577 = 501618
107 + 501511 = 501618
167 + 501451 = 501618
191 + 501427 = 501618
199 + 501419 = 501618
251 + 501367 = 501618
277 + 501341 = 501618

Showing the first eight; more decompositions exist.
