Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 513664, here are decompositions:

23 + 513641 = 513664
71 + 513593 = 513664
131 + 513533 = 513664
191 + 513473 = 513664
233 + 513431 = 513664
257 + 513407 = 513664
293 + 513371 = 513664
311 + 513353 = 513664

Showing the first eight; more decompositions exist.
