Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 64576, here are decompositions:

23 + 64553 = 64576
137 + 64439 = 64576
173 + 64403 = 64576
257 + 64319 = 64576
293 + 64283 = 64576
353 + 64223 = 64576
359 + 64217 = 64576
389 + 64187 = 64576

Showing the first eight; more decompositions exist.
