Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31608384, here are decompositions:

43 + 31608341 = 31608384
47 + 31608337 = 31608384
83 + 31608301 = 31608384
113 + 31608271 = 31608384
167 + 31608217 = 31608384
251 + 31608133 = 31608384
277 + 31608107 = 31608384
293 + 31608091 = 31608384

Showing the first eight; more decompositions exist.
