Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31608764, here are decompositions:

7 + 31608757 = 31608764
37 + 31608727 = 31608764
43 + 31608721 = 31608764
67 + 31608697 = 31608764
97 + 31608667 = 31608764
283 + 31608481 = 31608764
337 + 31608427 = 31608764
463 + 31608301 = 31608764

Showing the first eight; more decompositions exist.
