Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31602006, here are decompositions:

19 + 31601987 = 31602006
83 + 31601923 = 31602006
109 + 31601897 = 31602006
157 + 31601849 = 31602006
197 + 31601809 = 31602006
223 + 31601783 = 31602006
239 + 31601767 = 31602006
263 + 31601743 = 31602006

Showing the first eight; more decompositions exist.
