Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31602444, here are decompositions:

23 + 31602421 = 31602444
43 + 31602401 = 31602444
47 + 31602397 = 31602444
127 + 31602317 = 31602444
163 + 31602281 = 31602444
193 + 31602251 = 31602444
227 + 31602217 = 31602444
271 + 31602173 = 31602444

Showing the first eight; more decompositions exist.
