Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617358, here are decompositions:

29 + 31617329 = 31617358
89 + 31617269 = 31617358
107 + 31617251 = 31617358
191 + 31617167 = 31617358
257 + 31617101 = 31617358
281 + 31617077 = 31617358
347 + 31617011 = 31617358
359 + 31616999 = 31617358

Showing the first eight; more decompositions exist.
