Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 64512, here are decompositions:

13 + 64499 = 64512
23 + 64489 = 64512
29 + 64483 = 64512
59 + 64453 = 64512
61 + 64451 = 64512
73 + 64439 = 64512
79 + 64433 = 64512
109 + 64403 = 64512

Showing the first eight; more decompositions exist.
