Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31609082, here are decompositions:

3 + 31609079 = 31609082
199 + 31608883 = 31609082
229 + 31608853 = 31609082
601 + 31608481 = 31609082
733 + 31608349 = 31609082
811 + 31608271 = 31609082
919 + 31608163 = 31609082
991 + 31608091 = 31609082

Showing the first eight; more decompositions exist.
