Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532360, here are decompositions:

7 + 31532353 = 31532360
19 + 31532341 = 31532360
31 + 31532329 = 31532360
37 + 31532323 = 31532360
151 + 31532209 = 31532360
157 + 31532203 = 31532360
193 + 31532167 = 31532360
271 + 31532089 = 31532360

Showing the first eight; more decompositions exist.
