Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 22172, here are decompositions:

13 + 22159 = 22172
19 + 22153 = 22172
43 + 22129 = 22172
61 + 22111 = 22172
79 + 22093 = 22172
109 + 22063 = 22172
181 + 21991 = 22172
211 + 21961 = 22172

Showing the first eight; more decompositions exist.
