Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31602948, here are decompositions:

17 + 31602931 = 31602948
31 + 31602917 = 31602948
71 + 31602877 = 31602948
89 + 31602859 = 31602948
257 + 31602691 = 31602948
269 + 31602679 = 31602948
317 + 31602631 = 31602948
359 + 31602589 = 31602948

Showing the first eight; more decompositions exist.
