Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31609922, here are decompositions:

61 + 31609861 = 31609922
73 + 31609849 = 31609922
103 + 31609819 = 31609922
109 + 31609813 = 31609922
163 + 31609759 = 31609922
181 + 31609741 = 31609922
199 + 31609723 = 31609922
229 + 31609693 = 31609922

Showing the first eight; more decompositions exist.
