Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 151188, here are decompositions:

17 + 151171 = 151188
19 + 151169 = 151188
31 + 151157 = 151188
47 + 151141 = 151188
67 + 151121 = 151188
97 + 151091 = 151188
131 + 151057 = 151188
137 + 151051 = 151188

Showing the first eight; more decompositions exist.
