Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 513990, here are decompositions:

13 + 513977 = 513990
47 + 513943 = 513990
53 + 513937 = 513990
67 + 513923 = 513990
73 + 513917 = 513990
109 + 513881 = 513990
149 + 513841 = 513990
151 + 513839 = 513990

Showing the first eight; more decompositions exist.
