Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31609752, here are decompositions:

11 + 31609741 = 31609752
29 + 31609723 = 31609752
59 + 31609693 = 31609752
61 + 31609691 = 31609752
73 + 31609679 = 31609752
191 + 31609561 = 31609752
211 + 31609541 = 31609752
233 + 31609519 = 31609752

Showing the first eight; more decompositions exist.
