Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 63664, here are decompositions:

5 + 63659 = 63664
17 + 63647 = 63664
47 + 63617 = 63664
53 + 63611 = 63664
131 + 63533 = 63664
137 + 63527 = 63664
191 + 63473 = 63664
197 + 63467 = 63664

Showing the first eight; more decompositions exist.
