Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31602620, here are decompositions:

31 + 31602589 = 31602620
103 + 31602517 = 31602620
139 + 31602481 = 31602620
163 + 31602457 = 31602620
199 + 31602421 = 31602620
223 + 31602397 = 31602620
457 + 31602163 = 31602620
499 + 31602121 = 31602620

Showing the first eight; more decompositions exist.
