Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617348, here are decompositions:

19 + 31617329 = 31617348
67 + 31617281 = 31617348
79 + 31617269 = 31617348
97 + 31617251 = 31617348
109 + 31617239 = 31617348
149 + 31617199 = 31617348
167 + 31617181 = 31617348
181 + 31617167 = 31617348

Showing the first eight; more decompositions exist.
