Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 149286, here are decompositions:

17 + 149269 = 149286
29 + 149257 = 149286
37 + 149249 = 149286
47 + 149239 = 149286
73 + 149213 = 149286
89 + 149197 = 149286
103 + 149183 = 149286
113 + 149173 = 149286

Showing the first eight; more decompositions exist.
