Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31609916, here are decompositions:

67 + 31609849 = 31609916
97 + 31609819 = 31609916
103 + 31609813 = 31609916
139 + 31609777 = 31609916
157 + 31609759 = 31609916
193 + 31609723 = 31609916
223 + 31609693 = 31609916
307 + 31609609 = 31609916

Showing the first eight; more decompositions exist.
