Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31602388, here are decompositions:

71 + 31602317 = 31602388
107 + 31602281 = 31602388
137 + 31602251 = 31602388
149 + 31602239 = 31602388
317 + 31602071 = 31602388
347 + 31602041 = 31602388
401 + 31601987 = 31602388
491 + 31601897 = 31602388

Showing the first eight; more decompositions exist.
