Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31602474, here are decompositions:

17 + 31602457 = 31602474
23 + 31602451 = 31602474
31 + 31602443 = 31602474
53 + 31602421 = 31602474
73 + 31602401 = 31602474
107 + 31602367 = 31602474
151 + 31602323 = 31602474
157 + 31602317 = 31602474

Showing the first eight; more decompositions exist.
