Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31610792, here are decompositions:

13 + 31610779 = 31610792
19 + 31610773 = 31610792
151 + 31610641 = 31610792
163 + 31610629 = 31610792
211 + 31610581 = 31610792
223 + 31610569 = 31610792
229 + 31610563 = 31610792
271 + 31610521 = 31610792

Showing the first eight; more decompositions exist.
