Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 10112, here are decompositions:

13 + 10099 = 10112
19 + 10093 = 10112
43 + 10069 = 10112
73 + 10039 = 10112
103 + 10009 = 10112
139 + 9973 = 10112
163 + 9949 = 10112
181 + 9931 = 10112

Showing the first eight; more decompositions exist.
