Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31610022, here are decompositions:

11 + 31610011 = 31610022
13 + 31610009 = 31610022
29 + 31609993 = 31610022
89 + 31609933 = 31610022
139 + 31609883 = 31610022
151 + 31609871 = 31610022
173 + 31609849 = 31610022
229 + 31609793 = 31610022

Showing the first eight; more decompositions exist.
