Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31609074, here are decompositions:

41 + 31609033 = 31609074
43 + 31609031 = 31609074
103 + 31608971 = 31609074
137 + 31608937 = 31609074
157 + 31608917 = 31609074
163 + 31608911 = 31609074
181 + 31608893 = 31609074
191 + 31608883 = 31609074

Showing the first eight; more decompositions exist.
