Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532366, here are decompositions:

13 + 31532353 = 31532366
37 + 31532329 = 31532366
43 + 31532323 = 31532366
97 + 31532269 = 31532366
139 + 31532227 = 31532366
157 + 31532209 = 31532366
163 + 31532203 = 31532366
199 + 31532167 = 31532366

Showing the first eight; more decompositions exist.
