Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 148188, here are decompositions:

17 + 148171 = 148188
31 + 148157 = 148188
37 + 148151 = 148188
41 + 148147 = 148188
97 + 148091 = 148188
109 + 148079 = 148188
127 + 148061 = 148188
167 + 148021 = 148188

Showing the first eight; more decompositions exist.
