Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31602666, here are decompositions:

5 + 31602661 = 31602666
19 + 31602647 = 31602666
79 + 31602587 = 31602666
127 + 31602539 = 31602666
149 + 31602517 = 31602666
223 + 31602443 = 31602666
269 + 31602397 = 31602666
313 + 31602353 = 31602666

Showing the first eight; more decompositions exist.
