Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 503638, here are decompositions:

17 + 503621 = 503638
29 + 503609 = 503638
89 + 503549 = 503638
137 + 503501 = 503638
197 + 503441 = 503638
257 + 503381 = 503638
269 + 503369 = 503638
389 + 503249 = 503638

Showing the first eight; more decompositions exist.
