Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31602520, here are decompositions:

3 + 31602517 = 31602520
23 + 31602497 = 31602520
167 + 31602353 = 31602520
197 + 31602323 = 31602520
239 + 31602281 = 31602520
269 + 31602251 = 31602520
281 + 31602239 = 31602520
293 + 31602227 = 31602520

Showing the first eight; more decompositions exist.
