Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 503816, here are decompositions:

13 + 503803 = 503816
37 + 503779 = 503816
73 + 503743 = 503816
109 + 503707 = 503816
163 + 503653 = 503816
193 + 503623 = 503816
223 + 503593 = 503816
409 + 503407 = 503816

Showing the first eight; more decompositions exist.
