Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31608984, here are decompositions:

13 + 31608971 = 31608984
31 + 31608953 = 31608984
47 + 31608937 = 31608984
67 + 31608917 = 31608984
73 + 31608911 = 31608984
97 + 31608887 = 31608984
101 + 31608883 = 31608984
131 + 31608853 = 31608984

Showing the first eight; more decompositions exist.
