Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 503806, here are decompositions:

3 + 503803 = 503806
29 + 503777 = 503806
53 + 503753 = 503806
89 + 503717 = 503806
197 + 503609 = 503806
257 + 503549 = 503806
263 + 503543 = 503806
353 + 503453 = 503806

Showing the first eight; more decompositions exist.
