Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31602200, here are decompositions:

37 + 31602163 = 31602200
79 + 31602121 = 31602200
103 + 31602097 = 31602200
151 + 31602049 = 31602200
277 + 31601923 = 31602200
337 + 31601863 = 31602200
433 + 31601767 = 31602200
457 + 31601743 = 31602200

Showing the first eight; more decompositions exist.
