Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31611968, here are decompositions:

61 + 31611907 = 31611968
127 + 31611841 = 31611968
139 + 31611829 = 31611968
151 + 31611817 = 31611968
211 + 31611757 = 31611968
601 + 31611367 = 31611968
919 + 31611049 = 31611968
1327 + 31610641 = 31611968

Showing the first eight; more decompositions exist.
