Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31608846, here are decompositions:

23 + 31608823 = 31608846
29 + 31608817 = 31608846
53 + 31608793 = 31608846
67 + 31608779 = 31608846
89 + 31608757 = 31608846
97 + 31608749 = 31608846
109 + 31608737 = 31608846
149 + 31608697 = 31608846

Showing the first eight; more decompositions exist.
