Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31611168, here are decompositions:

5 + 31611163 = 31611168
31 + 31611137 = 31611168
41 + 31611127 = 31611168
67 + 31611101 = 31611168
79 + 31611089 = 31611168
101 + 31611067 = 31611168
131 + 31611037 = 31611168
139 + 31611029 = 31611168

Showing the first eight; more decompositions exist.
