Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 500638, here are decompositions:

59 + 500579 = 500638
71 + 500567 = 500638
137 + 500501 = 500638
167 + 500471 = 500638
179 + 500459 = 500638
269 + 500369 = 500638
317 + 500321 = 500638
389 + 500249 = 500638

Showing the first eight; more decompositions exist.
