Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616046, here are decompositions:

5 + 31616041 = 31616046
13 + 31616033 = 31616046
23 + 31616023 = 31616046
29 + 31616017 = 31616046
37 + 31616009 = 31616046
47 + 31615999 = 31616046
53 + 31615993 = 31616046
67 + 31615979 = 31616046

Showing the first eight; more decompositions exist.
