Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617550, here are decompositions:

17 + 31617533 = 31617550
47 + 31617503 = 31617550
53 + 31617497 = 31617550
89 + 31617461 = 31617550
101 + 31617449 = 31617550
137 + 31617413 = 31617550
179 + 31617371 = 31617550
257 + 31617293 = 31617550

Showing the first eight; more decompositions exist.
