Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 121158, here are decompositions:

7 + 121151 = 121158
19 + 121139 = 121158
97 + 121061 = 121158
137 + 121021 = 121158
139 + 121019 = 121158
151 + 121007 = 121158
157 + 121001 = 121158
181 + 120977 = 121158

Showing the first eight; more decompositions exist.
