Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31602836, here are decompositions:

43 + 31602793 = 31602836
73 + 31602763 = 31602836
157 + 31602679 = 31602836
163 + 31602673 = 31602836
379 + 31602457 = 31602836
439 + 31602397 = 31602836
619 + 31602217 = 31602836
673 + 31602163 = 31602836

Showing the first eight; more decompositions exist.
