Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31602940, here are decompositions:

23 + 31602917 = 31602940
41 + 31602899 = 31602940
137 + 31602803 = 31602940
251 + 31602689 = 31602940
293 + 31602647 = 31602940
353 + 31602587 = 31602940
359 + 31602581 = 31602940
401 + 31602539 = 31602940

Showing the first eight; more decompositions exist.
