Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 513984, here are decompositions:

7 + 513977 = 513984
41 + 513943 = 513984
47 + 513937 = 513984
61 + 513923 = 513984
67 + 513917 = 513984
103 + 513881 = 513984
113 + 513871 = 513984
223 + 513761 = 513984

Showing the first eight; more decompositions exist.
