Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31602942, here are decompositions:

11 + 31602931 = 31602942
43 + 31602899 = 31602942
79 + 31602863 = 31602942
83 + 31602859 = 31602942
89 + 31602853 = 31602942
139 + 31602803 = 31602942
149 + 31602793 = 31602942
179 + 31602763 = 31602942

Showing the first eight; more decompositions exist.
