Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 22640, here are decompositions:

3 + 22637 = 22640
19 + 22621 = 22640
67 + 22573 = 22640
73 + 22567 = 22640
97 + 22543 = 22640
109 + 22531 = 22640
139 + 22501 = 22640
157 + 22483 = 22640

Showing the first eight; more decompositions exist.
