Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616814, here are decompositions:

41 + 31616773 = 31616814
67 + 31616747 = 31616814
107 + 31616707 = 31616814
127 + 31616687 = 31616814
137 + 31616677 = 31616814
167 + 31616647 = 31616814
191 + 31616623 = 31616814
211 + 31616603 = 31616814

Showing the first eight; more decompositions exist.
