Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532238, here are decompositions:

11 + 31532227 = 31532238
19 + 31532219 = 31532238
29 + 31532209 = 31532238
71 + 31532167 = 31532238
97 + 31532141 = 31532238
149 + 31532089 = 31532238
167 + 31532071 = 31532238
271 + 31531967 = 31532238

Showing the first eight; more decompositions exist.
