Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31608606, here are decompositions:

17 + 31608589 = 31608606
19 + 31608587 = 31608606
79 + 31608527 = 31608606
109 + 31608497 = 31608606
157 + 31608449 = 31608606
179 + 31608427 = 31608606
257 + 31608349 = 31608606
269 + 31608337 = 31608606

Showing the first eight; more decompositions exist.
