Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31609062, here are decompositions:

13 + 31609049 = 31609062
29 + 31609033 = 31609062
31 + 31609031 = 31609062
103 + 31608959 = 31609062
109 + 31608953 = 31609062
151 + 31608911 = 31609062
179 + 31608883 = 31609062
211 + 31608851 = 31609062

Showing the first eight; more decompositions exist.
