Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31602342, here are decompositions:

19 + 31602323 = 31602342
61 + 31602281 = 31602342
103 + 31602239 = 31602342
179 + 31602163 = 31602342
199 + 31602143 = 31602342
263 + 31602079 = 31602342
271 + 31602071 = 31602342
293 + 31602049 = 31602342

Showing the first eight; more decompositions exist.
