Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607112, here are decompositions:

11 + 31607101 = 31607112
73 + 31607039 = 31607112
139 + 31606973 = 31607112
149 + 31606963 = 31607112
181 + 31606931 = 31607112
193 + 31606919 = 31607112
233 + 31606879 = 31607112
283 + 31606829 = 31607112

Showing the first eight; more decompositions exist.
