Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616676, here are decompositions:

5 + 31616671 = 31616676
29 + 31616647 = 31616676
53 + 31616623 = 31616676
73 + 31616603 = 31616676
97 + 31616579 = 31616676
107 + 31616569 = 31616676
137 + 31616539 = 31616676
167 + 31616509 = 31616676

Showing the first eight; more decompositions exist.
