Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31602694, here are decompositions:

3 + 31602691 = 31602694
5 + 31602689 = 31602694
47 + 31602647 = 31602694
107 + 31602587 = 31602694
113 + 31602581 = 31602694
173 + 31602521 = 31602694
197 + 31602497 = 31602694
251 + 31602443 = 31602694

Showing the first eight; more decompositions exist.
