Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31609832, here are decompositions:

13 + 31609819 = 31609832
19 + 31609813 = 31609832
73 + 31609759 = 31609832
109 + 31609723 = 31609832
139 + 31609693 = 31609832
223 + 31609609 = 31609832
271 + 31609561 = 31609832
283 + 31609549 = 31609832

Showing the first eight; more decompositions exist.
