Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616076, here are decompositions:

7 + 31616069 = 31616076
17 + 31616059 = 31616076
29 + 31616047 = 31616076
43 + 31616033 = 31616076
53 + 31616023 = 31616076
59 + 31616017 = 31616076
67 + 31616009 = 31616076
83 + 31615993 = 31616076

Showing the first eight; more decompositions exist.
