Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31602438, here are decompositions:

17 + 31602421 = 31602438
37 + 31602401 = 31602438
41 + 31602397 = 31602438
71 + 31602367 = 31602438
157 + 31602281 = 31602438
199 + 31602239 = 31602438
211 + 31602227 = 31602438
317 + 31602121 = 31602438

Showing the first eight; more decompositions exist.
