Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616910, here are decompositions:

7 + 31616903 = 31616910
19 + 31616891 = 31616910
23 + 31616887 = 31616910
53 + 31616857 = 31616910
71 + 31616839 = 31616910
137 + 31616773 = 31616910
163 + 31616747 = 31616910
181 + 31616729 = 31616910

Showing the first eight; more decompositions exist.
