Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532376, here are decompositions:

23 + 31532353 = 31532376
37 + 31532339 = 31532376
47 + 31532329 = 31532376
53 + 31532323 = 31532376
97 + 31532279 = 31532376
107 + 31532269 = 31532376
149 + 31532227 = 31532376
157 + 31532219 = 31532376

Showing the first eight; more decompositions exist.
