Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31456112, here are decompositions:

13 + 31456099 = 31456112
19 + 31456093 = 31456112
109 + 31456003 = 31456112
151 + 31455961 = 31456112
211 + 31455901 = 31456112
223 + 31455889 = 31456112
271 + 31455841 = 31456112
283 + 31455829 = 31456112

Showing the first eight; more decompositions exist.
