Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 112158, here are decompositions:

5 + 112153 = 112158
19 + 112139 = 112158
29 + 112129 = 112158
37 + 112121 = 112158
47 + 112111 = 112158
61 + 112097 = 112158
71 + 112087 = 112158
89 + 112069 = 112158

Showing the first eight; more decompositions exist.
