Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 529664, here are decompositions:

7 + 529657 = 529664
61 + 529603 = 529664
151 + 529513 = 529664
193 + 529471 = 529664
241 + 529423 = 529664
271 + 529393 = 529664
283 + 529381 = 529664
307 + 529357 = 529664

Showing the first eight; more decompositions exist.
