Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31610086, here are decompositions:

3 + 31610083 = 31610086
5 + 31610081 = 31610086
23 + 31610063 = 31610086
47 + 31610039 = 31610086
113 + 31609973 = 31610086
149 + 31609937 = 31610086
239 + 31609847 = 31610086
293 + 31609793 = 31610086

Showing the first eight; more decompositions exist.
