Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 505038, here are decompositions:

5 + 505033 = 505038
7 + 505031 = 505038
11 + 505027 = 505038
47 + 504991 = 505038
71 + 504967 = 505038
101 + 504937 = 505038
109 + 504929 = 505038
137 + 504901 = 505038

Showing the first eight; more decompositions exist.
