Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31602012, here are decompositions:

89 + 31601923 = 31602012
131 + 31601881 = 31602012
139 + 31601873 = 31602012
149 + 31601863 = 31602012
163 + 31601849 = 31602012
193 + 31601819 = 31602012
229 + 31601783 = 31602012
269 + 31601743 = 31602012

Showing the first eight; more decompositions exist.
