Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 503978, here are decompositions:

19 + 503959 = 503978
31 + 503947 = 503978
67 + 503911 = 503978
109 + 503869 = 503978
127 + 503851 = 503978
151 + 503827 = 503978
157 + 503821 = 503978
199 + 503779 = 503978

Showing the first eight; more decompositions exist.
