Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 503216, here are decompositions:

3 + 503213 = 503216
19 + 503197 = 503216
79 + 503137 = 503216
139 + 503077 = 503216
163 + 503053 = 503216
199 + 503017 = 503216
397 + 502819 = 503216
409 + 502807 = 503216

Showing the first eight; more decompositions exist.
