Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31602540, here are decompositions:

19 + 31602521 = 31602540
23 + 31602517 = 31602540
43 + 31602497 = 31602540
59 + 31602481 = 31602540
83 + 31602457 = 31602540
89 + 31602451 = 31602540
97 + 31602443 = 31602540
139 + 31602401 = 31602540

Showing the first eight; more decompositions exist.
