Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31566996, here are decompositions:

17 + 31566979 = 31566996
23 + 31566973 = 31566996
29 + 31566967 = 31566996
157 + 31566839 = 31566996
179 + 31566817 = 31566996
193 + 31566803 = 31566996
199 + 31566797 = 31566996
233 + 31566763 = 31566996

Showing the first eight; more decompositions exist.
