Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 500518, here are decompositions:

17 + 500501 = 500518
47 + 500471 = 500518
59 + 500459 = 500518
101 + 500417 = 500518
149 + 500369 = 500518
197 + 500321 = 500518
269 + 500249 = 500518
281 + 500237 = 500518

Showing the first eight; more decompositions exist.
