Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 64456, here are decompositions:

3 + 64453 = 64456
5 + 64451 = 64456
17 + 64439 = 64456
23 + 64433 = 64456
53 + 64403 = 64456
83 + 64373 = 64456
137 + 64319 = 64456
173 + 64283 = 64456

Showing the first eight; more decompositions exist.
