Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31609734, here are decompositions:

11 + 31609723 = 31609734
31 + 31609703 = 31609734
41 + 31609693 = 31609734
43 + 31609691 = 31609734
73 + 31609661 = 31609734
103 + 31609631 = 31609734
151 + 31609583 = 31609734
157 + 31609577 = 31609734

Showing the first eight; more decompositions exist.
