Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 500388, here are decompositions:

19 + 500369 = 500388
47 + 500341 = 500388
67 + 500321 = 500388
71 + 500317 = 500388
89 + 500299 = 500388
101 + 500287 = 500388
131 + 500257 = 500388
139 + 500249 = 500388

Showing the first eight; more decompositions exist.
