Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31602536, here are decompositions:

19 + 31602517 = 31602536
79 + 31602457 = 31602536
139 + 31602397 = 31602536
373 + 31602163 = 31602536
439 + 31602097 = 31602536
457 + 31602079 = 31602536
487 + 31602049 = 31602536
613 + 31601923 = 31602536

Showing the first eight; more decompositions exist.
