Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31608924, here are decompositions:

7 + 31608917 = 31608924
13 + 31608911 = 31608924
31 + 31608893 = 31608924
37 + 31608887 = 31608924
41 + 31608883 = 31608924
71 + 31608853 = 31608924
73 + 31608851 = 31608924
101 + 31608823 = 31608924

Showing the first eight; more decompositions exist.
