Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 148158, here are decompositions:

5 + 148153 = 148158
7 + 148151 = 148158
11 + 148147 = 148158
19 + 148139 = 148158
67 + 148091 = 148158
79 + 148079 = 148158
97 + 148061 = 148158
137 + 148021 = 148158

Showing the first eight; more decompositions exist.
