Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 503986, here are decompositions:

3 + 503983 = 503986
17 + 503969 = 503986
23 + 503963 = 503986
47 + 503939 = 503986
59 + 503927 = 503986
107 + 503879 = 503986
167 + 503819 = 503986
233 + 503753 = 503986

Showing the first eight; more decompositions exist.
