Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 113172, here are decompositions:

5 + 113167 = 113172
11 + 113161 = 113172
13 + 113159 = 113172
19 + 113153 = 113172
23 + 113149 = 113172
29 + 113143 = 113172
41 + 113131 = 113172
61 + 113111 = 113172

Showing the first eight; more decompositions exist.
