Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 9122, here are decompositions:

13 + 9109 = 9122
19 + 9103 = 9122
31 + 9091 = 9122
73 + 9049 = 9122
79 + 9043 = 9122
109 + 9013 = 9122
151 + 8971 = 9122
181 + 8941 = 9122

Showing the first eight; more decompositions exist.
