Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31608090, here are decompositions:

23 + 31608067 = 31608090
29 + 31608061 = 31608090
43 + 31608047 = 31608090
53 + 31608037 = 31608090
61 + 31608029 = 31608090
181 + 31607909 = 31608090
193 + 31607897 = 31608090
223 + 31607867 = 31608090

Showing the first eight; more decompositions exist.
