Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617402, here are decompositions:

23 + 31617379 = 31617402
29 + 31617373 = 31617402
31 + 31617371 = 31617402
41 + 31617361 = 31617402
73 + 31617329 = 31617402
109 + 31617293 = 31617402
149 + 31617253 = 31617402
151 + 31617251 = 31617402

Showing the first eight; more decompositions exist.
