Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31602454, here are decompositions:

3 + 31602451 = 31602454
11 + 31602443 = 31602454
53 + 31602401 = 31602454
101 + 31602353 = 31602454
131 + 31602323 = 31602454
137 + 31602317 = 31602454
173 + 31602281 = 31602454
227 + 31602227 = 31602454

Showing the first eight; more decompositions exist.
