Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616482, here are decompositions:

3 + 31616479 = 31616482
59 + 31616423 = 31616482
71 + 31616411 = 31616482
89 + 31616393 = 31616482
101 + 31616381 = 31616482
113 + 31616369 = 31616482
251 + 31616231 = 31616482
263 + 31616219 = 31616482

Showing the first eight; more decompositions exist.
