Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 186146, here are decompositions:

43 + 186103 = 186146
97 + 186049 = 186146
109 + 186037 = 186146
127 + 186019 = 186146
139 + 186007 = 186146
199 + 185947 = 186146
223 + 185923 = 186146
229 + 185917 = 186146

Showing the first eight; more decompositions exist.
