Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31602418, here are decompositions:

17 + 31602401 = 31602418
101 + 31602317 = 31602418
137 + 31602281 = 31602418
167 + 31602251 = 31602418
179 + 31602239 = 31602418
191 + 31602227 = 31602418
347 + 31602071 = 31602418
401 + 31602017 = 31602418

Showing the first eight; more decompositions exist.
