Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31608348, here are decompositions:

7 + 31608341 = 31608348
11 + 31608337 = 31608348
29 + 31608319 = 31608348
47 + 31608301 = 31608348
131 + 31608217 = 31608348
179 + 31608169 = 31608348
181 + 31608167 = 31608348
199 + 31608149 = 31608348

Showing the first eight; more decompositions exist.
