Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31602660, here are decompositions:

13 + 31602647 = 31602660
29 + 31602631 = 31602660
71 + 31602589 = 31602660
73 + 31602587 = 31602660
79 + 31602581 = 31602660
139 + 31602521 = 31602660
163 + 31602497 = 31602660
179 + 31602481 = 31602660

Showing the first eight; more decompositions exist.
