Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 103112, here are decompositions:

13 + 103099 = 103112
19 + 103093 = 103112
43 + 103069 = 103112
181 + 102931 = 103112
199 + 102913 = 103112
241 + 102871 = 103112
271 + 102841 = 103112
283 + 102829 = 103112

Showing the first eight; more decompositions exist.
