Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31609896, here are decompositions:

13 + 31609883 = 31609896
47 + 31609849 = 31609896
83 + 31609813 = 31609896
103 + 31609793 = 31609896
127 + 31609769 = 31609896
137 + 31609759 = 31609896
173 + 31609723 = 31609896
193 + 31609703 = 31609896

Showing the first eight; more decompositions exist.
