Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 513384, here are decompositions:

13 + 513371 = 513384
17 + 513367 = 513384
31 + 513353 = 513384
37 + 513347 = 513384
43 + 513341 = 513384
71 + 513313 = 513384
73 + 513311 = 513384
101 + 513283 = 513384

Showing the first eight; more decompositions exist.
