Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 503656, here are decompositions:

3 + 503653 = 503656
47 + 503609 = 503656
107 + 503549 = 503656
113 + 503543 = 503656
173 + 503483 = 503656
233 + 503423 = 503656
317 + 503339 = 503656
353 + 503303 = 503656

Showing the first eight; more decompositions exist.
