Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 113180, here are decompositions:

3 + 113177 = 113180
7 + 113173 = 113180
13 + 113167 = 113180
19 + 113161 = 113180
31 + 113149 = 113180
37 + 113143 = 113180
97 + 113083 = 113180
139 + 113041 = 113180

Showing the first eight; more decompositions exist.
