Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31609094, here are decompositions:

3 + 31609091 = 31609094
7 + 31609087 = 31609094
61 + 31609033 = 31609094
157 + 31608937 = 31609094
211 + 31608883 = 31609094
241 + 31608853 = 31609094
271 + 31608823 = 31609094
277 + 31608817 = 31609094

Showing the first eight; more decompositions exist.
