Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31609104, here are decompositions:

11 + 31609093 = 31609104
13 + 31609091 = 31609104
17 + 31609087 = 31609104
71 + 31609033 = 31609104
73 + 31609031 = 31609104
151 + 31608953 = 31609104
167 + 31608937 = 31609104
193 + 31608911 = 31609104

Showing the first eight; more decompositions exist.
