Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31608354, here are decompositions:

5 + 31608349 = 31608354
13 + 31608341 = 31608354
17 + 31608337 = 31608354
53 + 31608301 = 31608354
83 + 31608271 = 31608354
137 + 31608217 = 31608354
191 + 31608163 = 31608354
223 + 31608131 = 31608354

Showing the first eight; more decompositions exist.
