Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617526, here are decompositions:

23 + 31617503 = 31617526
29 + 31617497 = 31617526
113 + 31617413 = 31617526
197 + 31617329 = 31617526
233 + 31617293 = 31617526
257 + 31617269 = 31617526
359 + 31617167 = 31617526
449 + 31617077 = 31617526

Showing the first eight; more decompositions exist.
