Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31610080, here are decompositions:

17 + 31610063 = 31610080
41 + 31610039 = 31610080
71 + 31610009 = 31610080
107 + 31609973 = 31610080
113 + 31609967 = 31610080
149 + 31609931 = 31610080
197 + 31609883 = 31610080
233 + 31609847 = 31610080

Showing the first eight; more decompositions exist.
