Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31608356, here are decompositions:

7 + 31608349 = 31608356
19 + 31608337 = 31608356
37 + 31608319 = 31608356
139 + 31608217 = 31608356
193 + 31608163 = 31608356
223 + 31608133 = 31608356
487 + 31607869 = 31608356
499 + 31607857 = 31608356

Showing the first eight; more decompositions exist.
