Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616424, here are decompositions:

5 + 31616419 = 31616424
13 + 31616411 = 31616424
23 + 31616401 = 31616424
31 + 31616393 = 31616424
43 + 31616381 = 31616424
61 + 31616363 = 31616424
97 + 31616327 = 31616424
127 + 31616297 = 31616424

Showing the first eight; more decompositions exist.
