Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31609050, here are decompositions:

17 + 31609033 = 31609050
19 + 31609031 = 31609050
79 + 31608971 = 31609050
97 + 31608953 = 31609050
113 + 31608937 = 31609050
139 + 31608911 = 31609050
157 + 31608893 = 31609050
163 + 31608887 = 31609050

Showing the first eight; more decompositions exist.
