Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31602456, here are decompositions:

5 + 31602451 = 31602456
13 + 31602443 = 31602456
59 + 31602397 = 31602456
89 + 31602367 = 31602456
103 + 31602353 = 31602456
139 + 31602317 = 31602456
229 + 31602227 = 31602456
239 + 31602217 = 31602456

Showing the first eight; more decompositions exist.
