Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31610014, here are decompositions:

3 + 31610011 = 31610014
5 + 31610009 = 31610014
41 + 31609973 = 31610014
47 + 31609967 = 31610014
83 + 31609931 = 31610014
131 + 31609883 = 31610014
167 + 31609847 = 31610014
311 + 31609703 = 31610014

Showing the first eight; more decompositions exist.
