Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31608936, here are decompositions:

19 + 31608917 = 31608936
43 + 31608893 = 31608936
53 + 31608883 = 31608936
83 + 31608853 = 31608936
113 + 31608823 = 31608936
157 + 31608779 = 31608936
179 + 31608757 = 31608936
199 + 31608737 = 31608936

Showing the first eight; more decompositions exist.
