Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 130236, here are decompositions:

13 + 130223 = 130236
37 + 130199 = 130236
53 + 130183 = 130236
89 + 130147 = 130236
109 + 130127 = 130236
137 + 130099 = 130236
149 + 130087 = 130236
157 + 130079 = 130236

Showing the first eight; more decompositions exist.
