Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8122, here are decompositions:

5 + 8117 = 8122
11 + 8111 = 8122
29 + 8093 = 8122
41 + 8081 = 8122
53 + 8069 = 8122
83 + 8039 = 8122
113 + 8009 = 8122
173 + 7949 = 8122

Showing the first eight; more decompositions exist.
