Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 508636, here are decompositions:

17 + 508619 = 508636
53 + 508583 = 508636
59 + 508577 = 508636
137 + 508499 = 508636
197 + 508439 = 508636
263 + 508373 = 508636
269 + 508367 = 508636
449 + 508187 = 508636

Showing the first eight; more decompositions exist.
