Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31606704, here are decompositions:

7 + 31606697 = 31606704
13 + 31606691 = 31606704
23 + 31606681 = 31606704
37 + 31606667 = 31606704
43 + 31606661 = 31606704
47 + 31606657 = 31606704
53 + 31606651 = 31606704
61 + 31606643 = 31606704

Showing the first eight; more decompositions exist.
