Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 988158, here are decompositions:

11 + 988147 = 988158
29 + 988129 = 988158
47 + 988111 = 988158
89 + 988069 = 988158
97 + 988061 = 988158
107 + 988051 = 988158
137 + 988021 = 988158
151 + 988007 = 988158

Showing the first eight; more decompositions exist.
