Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31608996, here are decompositions:

37 + 31608959 = 31608996
43 + 31608953 = 31608996
59 + 31608937 = 31608996
79 + 31608917 = 31608996
103 + 31608893 = 31608996
109 + 31608887 = 31608996
113 + 31608883 = 31608996
173 + 31608823 = 31608996

Showing the first eight; more decompositions exist.
