Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 501518, here are decompositions:

7 + 501511 = 501518
67 + 501451 = 501518
109 + 501409 = 501518
151 + 501367 = 501518
331 + 501187 = 501518
379 + 501139 = 501518
397 + 501121 = 501518
487 + 501031 = 501518

Showing the first eight; more decompositions exist.
