Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31610146, here are decompositions:

3 + 31610143 = 31610146
5 + 31610141 = 31610146
53 + 31610093 = 31610146
83 + 31610063 = 31610146
107 + 31610039 = 31610146
137 + 31610009 = 31610146
173 + 31609973 = 31610146
179 + 31609967 = 31610146

Showing the first eight; more decompositions exist.
