Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31602586, here are decompositions:

5 + 31602581 = 31602586
47 + 31602539 = 31602586
89 + 31602497 = 31602586
233 + 31602353 = 31602586
263 + 31602323 = 31602586
269 + 31602317 = 31602586
347 + 31602239 = 31602586
359 + 31602227 = 31602586

Showing the first eight; more decompositions exist.
