Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 63640, here are decompositions:

11 + 63629 = 63640
23 + 63617 = 63640
29 + 63611 = 63640
41 + 63599 = 63640
53 + 63587 = 63640
107 + 63533 = 63640
113 + 63527 = 63640
167 + 63473 = 63640

Showing the first eight; more decompositions exist.
