Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 503028, here are decompositions:

11 + 503017 = 503028
67 + 502961 = 503028
107 + 502921 = 503028
109 + 502919 = 503028
167 + 502861 = 503028
181 + 502847 = 503028
199 + 502829 = 503028
241 + 502787 = 503028

Showing the first eight; more decompositions exist.
