Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31608804, here are decompositions:

11 + 31608793 = 31608804
47 + 31608757 = 31608804
67 + 31608737 = 31608804
83 + 31608721 = 31608804
107 + 31608697 = 31608804
137 + 31608667 = 31608804
277 + 31608527 = 31608804
307 + 31608497 = 31608804

Showing the first eight; more decompositions exist.
