Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31608344, here are decompositions:

3 + 31608341 = 31608344
7 + 31608337 = 31608344
43 + 31608301 = 31608344
73 + 31608271 = 31608344
127 + 31608217 = 31608344
181 + 31608163 = 31608344
211 + 31608133 = 31608344
277 + 31608067 = 31608344

Showing the first eight; more decompositions exist.
