Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31602340, here are decompositions:

17 + 31602323 = 31602340
23 + 31602317 = 31602340
59 + 31602281 = 31602340
89 + 31602251 = 31602340
101 + 31602239 = 31602340
113 + 31602227 = 31602340
167 + 31602173 = 31602340
197 + 31602143 = 31602340

Showing the first eight; more decompositions exist.
