Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31606960, here are decompositions:

3 + 31606957 = 31606960
17 + 31606943 = 31606960
29 + 31606931 = 31606960
41 + 31606919 = 31606960
113 + 31606847 = 31606960
131 + 31606829 = 31606960
149 + 31606811 = 31606960
233 + 31606727 = 31606960

Showing the first eight; more decompositions exist.
