Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31610176, here are decompositions:

5 + 31610171 = 31610176
83 + 31610093 = 31610176
113 + 31610063 = 31610176
137 + 31610039 = 31610176
167 + 31610009 = 31610176
239 + 31609937 = 31610176
293 + 31609883 = 31610176
383 + 31609793 = 31610176

Showing the first eight; more decompositions exist.
