Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 189144, here are decompositions:

5 + 189139 = 189144
17 + 189127 = 189144
83 + 189061 = 189144
101 + 189043 = 189144
103 + 189041 = 189144
127 + 189017 = 189144
191 + 188953 = 189144
211 + 188933 = 189144

Showing the first eight; more decompositions exist.
