Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31610164, here are decompositions:

23 + 31610141 = 31610164
71 + 31610093 = 31610164
83 + 31610081 = 31610164
101 + 31610063 = 31610164
191 + 31609973 = 31610164
197 + 31609967 = 31610164
227 + 31609937 = 31610164
233 + 31609931 = 31610164

Showing the first eight; more decompositions exist.
