Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31609722, here are decompositions:

19 + 31609703 = 31609722
29 + 31609693 = 31609722
31 + 31609691 = 31609722
43 + 31609679 = 31609722
61 + 31609661 = 31609722
113 + 31609609 = 31609722
139 + 31609583 = 31609722
173 + 31609549 = 31609722

Showing the first eight; more decompositions exist.
