Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 503818, here are decompositions:

41 + 503777 = 503818
47 + 503771 = 503818
101 + 503717 = 503818
197 + 503621 = 503818
269 + 503549 = 503818
317 + 503501 = 503818
449 + 503369 = 503818
467 + 503351 = 503818

Showing the first eight; more decompositions exist.
