Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616016, here are decompositions:

7 + 31616009 = 31616016
17 + 31615999 = 31616016
23 + 31615993 = 31616016
37 + 31615979 = 31616016
43 + 31615973 = 31616016
97 + 31615919 = 31616016
167 + 31615849 = 31616016
233 + 31615783 = 31616016

Showing the first eight; more decompositions exist.
