Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617406, here are decompositions:

3 + 31617403 = 31617406
113 + 31617293 = 31617406
137 + 31617269 = 31617406
167 + 31617239 = 31617406
239 + 31617167 = 31617406
257 + 31617149 = 31617406
383 + 31617023 = 31617406
419 + 31616987 = 31617406

Showing the first eight; more decompositions exist.
