Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31608904, here are decompositions:

11 + 31608893 = 31608904
17 + 31608887 = 31608904
53 + 31608851 = 31608904
83 + 31608821 = 31608904
167 + 31608737 = 31608904
191 + 31608713 = 31608904
317 + 31608587 = 31608904
563 + 31608341 = 31608904

Showing the first eight; more decompositions exist.
