Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617376, here are decompositions:

3 + 31617373 = 31617376
5 + 31617371 = 31617376
47 + 31617329 = 31617376
83 + 31617293 = 31617376
107 + 31617269 = 31617376
137 + 31617239 = 31617376
227 + 31617149 = 31617376
347 + 31617029 = 31617376

Showing the first eight; more decompositions exist.
