Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617476, here are decompositions:

19 + 31617457 = 31617476
67 + 31617409 = 31617476
73 + 31617403 = 31617476
97 + 31617379 = 31617476
103 + 31617373 = 31617476
193 + 31617283 = 31617476
223 + 31617253 = 31617476
277 + 31617199 = 31617476

Showing the first eight; more decompositions exist.
