Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31602490, here are decompositions:

47 + 31602443 = 31602490
89 + 31602401 = 31602490
137 + 31602353 = 31602490
167 + 31602323 = 31602490
173 + 31602317 = 31602490
239 + 31602251 = 31602490
251 + 31602239 = 31602490
263 + 31602227 = 31602490

Showing the first eight; more decompositions exist.
