Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33640, here are decompositions:

3 + 33637 = 33640
11 + 33629 = 33640
17 + 33623 = 33640
23 + 33617 = 33640
41 + 33599 = 33640
53 + 33587 = 33640
59 + 33581 = 33640
71 + 33569 = 33640

Showing the first eight; more decompositions exist.
