Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616666, here are decompositions:

19 + 31616647 = 31616666
43 + 31616623 = 31616666
97 + 31616569 = 31616666
127 + 31616539 = 31616666
157 + 31616509 = 31616666
307 + 31616359 = 31616666
379 + 31616287 = 31616666
409 + 31616257 = 31616666

Showing the first eight; more decompositions exist.
