Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31602502, here are decompositions:

5 + 31602497 = 31602502
59 + 31602443 = 31602502
101 + 31602401 = 31602502
149 + 31602353 = 31602502
179 + 31602323 = 31602502
251 + 31602251 = 31602502
263 + 31602239 = 31602502
359 + 31602143 = 31602502

Showing the first eight; more decompositions exist.
