Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31602510, here are decompositions:

13 + 31602497 = 31602510
29 + 31602481 = 31602510
53 + 31602457 = 31602510
59 + 31602451 = 31602510
67 + 31602443 = 31602510
89 + 31602421 = 31602510
109 + 31602401 = 31602510
113 + 31602397 = 31602510

Showing the first eight; more decompositions exist.
