Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 189156, here are decompositions:

5 + 189151 = 189156
7 + 189149 = 189156
17 + 189139 = 189156
29 + 189127 = 189156
89 + 189067 = 189156
113 + 189043 = 189156
137 + 189019 = 189156
139 + 189017 = 189156

Showing the first eight; more decompositions exist.
