Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31608444, here are decompositions:

17 + 31608427 = 31608444
103 + 31608341 = 31608444
107 + 31608337 = 31608444
173 + 31608271 = 31608444
181 + 31608263 = 31608444
227 + 31608217 = 31608444
277 + 31608167 = 31608444
281 + 31608163 = 31608444

Showing the first eight; more decompositions exist.
