Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31602030, here are decompositions:

13 + 31602017 = 31602030
43 + 31601987 = 31602030
107 + 31601923 = 31602030
139 + 31601891 = 31602030
149 + 31601881 = 31602030
157 + 31601873 = 31602030
167 + 31601863 = 31602030
181 + 31601849 = 31602030

Showing the first eight; more decompositions exist.
