Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31608066, here are decompositions:

5 + 31608061 = 31608066
19 + 31608047 = 31608066
29 + 31608037 = 31608066
37 + 31608029 = 31608066
53 + 31608013 = 31608066
97 + 31607969 = 31608066
157 + 31607909 = 31608066
163 + 31607903 = 31608066

Showing the first eight; more decompositions exist.
