Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 503988, here are decompositions:

5 + 503983 = 503988
19 + 503969 = 503988
29 + 503959 = 503988
41 + 503947 = 503988
59 + 503929 = 503988
61 + 503927 = 503988
109 + 503879 = 503988
131 + 503857 = 503988

Showing the first eight; more decompositions exist.
