Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31609758, here are decompositions:

17 + 31609741 = 31609758
67 + 31609691 = 31609758
79 + 31609679 = 31609758
97 + 31609661 = 31609758
127 + 31609631 = 31609758
149 + 31609609 = 31609758
181 + 31609577 = 31609758
197 + 31609561 = 31609758

Showing the first eight; more decompositions exist.
