Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596888, here are decompositions:

5 + 31596883 = 31596888
7 + 31596881 = 31596888
31 + 31596857 = 31596888
41 + 31596847 = 31596888
67 + 31596821 = 31596888
131 + 31596757 = 31596888
137 + 31596751 = 31596888
139 + 31596749 = 31596888

Showing the first eight; more decompositions exist.
