Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 189162, here are decompositions:

11 + 189151 = 189162
13 + 189149 = 189162
23 + 189139 = 189162
101 + 189061 = 189162
151 + 189011 = 189162
163 + 188999 = 189162
179 + 188983 = 189162
223 + 188939 = 189162

Showing the first eight; more decompositions exist.
