Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 189146, here are decompositions:

7 + 189139 = 189146
19 + 189127 = 189146
79 + 189067 = 189146
103 + 189043 = 189146
127 + 189019 = 189146
163 + 188983 = 189146
193 + 188953 = 189146
277 + 188869 = 189146

Showing the first eight; more decompositions exist.
