Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 500386, here are decompositions:

17 + 500369 = 500386
23 + 500363 = 500386
53 + 500333 = 500386
137 + 500249 = 500386
149 + 500237 = 500386
233 + 500153 = 500386
317 + 500069 = 500386
443 + 499943 = 500386

Showing the first eight; more decompositions exist.
