Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 503666, here are decompositions:

3 + 503663 = 503666
13 + 503653 = 503666
19 + 503647 = 503666
43 + 503623 = 503666
67 + 503599 = 503666
73 + 503593 = 503666
103 + 503563 = 503666
277 + 503389 = 503666

Showing the first eight; more decompositions exist.
