Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31610088, here are decompositions:

5 + 31610083 = 31610088
7 + 31610081 = 31610088
79 + 31610009 = 31610088
131 + 31609957 = 31610088
151 + 31609937 = 31610088
157 + 31609931 = 31610088
227 + 31609861 = 31610088
239 + 31609849 = 31610088

Showing the first eight; more decompositions exist.
