Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 22738, here are decompositions:

11 + 22727 = 22738
17 + 22721 = 22738
29 + 22709 = 22738
41 + 22697 = 22738
47 + 22691 = 22738
59 + 22679 = 22738
101 + 22637 = 22738
167 + 22571 = 22738

Showing the first eight; more decompositions exist.
