Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 22040, here are decompositions:

3 + 22037 = 22040
13 + 22027 = 22040
37 + 22003 = 22040
43 + 21997 = 22040
79 + 21961 = 22040
97 + 21943 = 22040
103 + 21937 = 22040
181 + 21859 = 22040

Showing the first eight; more decompositions exist.
