Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 64480, here are decompositions:

29 + 64451 = 64480
41 + 64439 = 64480
47 + 64433 = 64480
107 + 64373 = 64480
179 + 64301 = 64480
197 + 64283 = 64480
257 + 64223 = 64480
263 + 64217 = 64480

Showing the first eight; more decompositions exist.
