Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31602500, here are decompositions:

3 + 31602497 = 31602500
19 + 31602481 = 31602500
43 + 31602457 = 31602500
79 + 31602421 = 31602500
103 + 31602397 = 31602500
283 + 31602217 = 31602500
337 + 31602163 = 31602500
379 + 31602121 = 31602500

Showing the first eight; more decompositions exist.
