Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31602522, here are decompositions:

5 + 31602517 = 31602522
41 + 31602481 = 31602522
71 + 31602451 = 31602522
79 + 31602443 = 31602522
101 + 31602421 = 31602522
199 + 31602323 = 31602522
241 + 31602281 = 31602522
271 + 31602251 = 31602522

Showing the first eight; more decompositions exist.
