Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 22156, here are decompositions:

3 + 22153 = 22156
23 + 22133 = 22156
47 + 22109 = 22156
83 + 22073 = 22156
89 + 22067 = 22156
179 + 21977 = 22156
227 + 21929 = 22156
263 + 21893 = 22156

Showing the first eight; more decompositions exist.
