Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31606968, here are decompositions:

5 + 31606963 = 31606968
11 + 31606957 = 31606968
17 + 31606951 = 31606968
37 + 31606931 = 31606968
89 + 31606879 = 31606968
139 + 31606829 = 31606968
157 + 31606811 = 31606968
227 + 31606741 = 31606968

Showing the first eight; more decompositions exist.
