Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 503636, here are decompositions:

13 + 503623 = 503636
37 + 503599 = 503636
43 + 503593 = 503636
73 + 503563 = 503636
223 + 503413 = 503636
229 + 503407 = 503636
277 + 503359 = 503636
349 + 503287 = 503636

Showing the first eight; more decompositions exist.
