Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 503218, here are decompositions:

5 + 503213 = 503218
11 + 503207 = 503218
59 + 503159 = 503218
71 + 503147 = 503218
179 + 503039 = 503218
257 + 502961 = 503218
281 + 502937 = 503218
389 + 502829 = 503218

Showing the first eight; more decompositions exist.
