Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31610012, here are decompositions:

3 + 31610009 = 31610012
19 + 31609993 = 31610012
79 + 31609933 = 31610012
151 + 31609861 = 31610012
163 + 31609849 = 31610012
193 + 31609819 = 31610012
199 + 31609813 = 31610012
271 + 31609741 = 31610012

Showing the first eight; more decompositions exist.
