Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 513504, here are decompositions:

23 + 513481 = 513504
31 + 513473 = 513504
73 + 513431 = 513504
97 + 513407 = 513504
107 + 513397 = 513504
137 + 513367 = 513504
151 + 513353 = 513504
157 + 513347 = 513504

Showing the first eight; more decompositions exist.
