Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31516112, here are decompositions:

3 + 31516109 = 31516112
13 + 31516099 = 31516112
31 + 31516081 = 31516112
163 + 31515949 = 31516112
181 + 31515931 = 31516112
193 + 31515919 = 31516112
349 + 31515763 = 31516112
379 + 31515733 = 31516112

Showing the first eight; more decompositions exist.
