Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31566162, here are decompositions:

11 + 31566151 = 31566162
31 + 31566131 = 31566162
79 + 31566083 = 31566162
83 + 31566079 = 31566162
101 + 31566061 = 31566162
149 + 31566013 = 31566162
181 + 31565981 = 31566162
191 + 31565971 = 31566162

Showing the first eight; more decompositions exist.
