Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31609764, here are decompositions:

5 + 31609759 = 31609764
23 + 31609741 = 31609764
41 + 31609723 = 31609764
61 + 31609703 = 31609764
71 + 31609693 = 31609764
73 + 31609691 = 31609764
103 + 31609661 = 31609764
181 + 31609583 = 31609764

Showing the first eight; more decompositions exist.
