Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31608954, here are decompositions:

17 + 31608937 = 31608954
37 + 31608917 = 31608954
43 + 31608911 = 31608954
61 + 31608893 = 31608954
67 + 31608887 = 31608954
71 + 31608883 = 31608954
101 + 31608853 = 31608954
103 + 31608851 = 31608954

Showing the first eight; more decompositions exist.
