Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533996, here are decompositions:

17 + 31533979 = 31533996
29 + 31533967 = 31533996
37 + 31533959 = 31533996
47 + 31533949 = 31533996
73 + 31533923 = 31533996
149 + 31533847 = 31533996
157 + 31533839 = 31533996
163 + 31533833 = 31533996

Showing the first eight; more decompositions exist.
