Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 113178, here are decompositions:

5 + 113173 = 113178
7 + 113171 = 113178
11 + 113167 = 113178
17 + 113161 = 113178
19 + 113159 = 113178
29 + 113149 = 113178
31 + 113147 = 113178
47 + 113131 = 113178

Showing the first eight; more decompositions exist.
