Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 503990, here are decompositions:

7 + 503983 = 503990
31 + 503959 = 503990
43 + 503947 = 503990
61 + 503929 = 503990
79 + 503911 = 503990
139 + 503851 = 503990
163 + 503827 = 503990
199 + 503791 = 503990

Showing the first eight; more decompositions exist.
