Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616508, here are decompositions:

29 + 31616479 = 31616508
89 + 31616419 = 31616508
97 + 31616411 = 31616508
107 + 31616401 = 31616508
127 + 31616381 = 31616508
139 + 31616369 = 31616508
149 + 31616359 = 31616508
181 + 31616327 = 31616508

Showing the first eight; more decompositions exist.
