Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617346, here are decompositions:

17 + 31617329 = 31617346
53 + 31617293 = 31617346
107 + 31617239 = 31617346
179 + 31617167 = 31617346
197 + 31617149 = 31617346
269 + 31617077 = 31617346
317 + 31617029 = 31617346
347 + 31616999 = 31617346

Showing the first eight; more decompositions exist.
