Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31602402, here are decompositions:

5 + 31602397 = 31602402
79 + 31602323 = 31602402
151 + 31602251 = 31602402
163 + 31602239 = 31602402
229 + 31602173 = 31602402
239 + 31602163 = 31602402
281 + 31602121 = 31602402
331 + 31602071 = 31602402

Showing the first eight; more decompositions exist.
