Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536372, here are decompositions:

11 + 31536361 = 31536372
13 + 31536359 = 31536372
19 + 31536353 = 31536372
59 + 31536313 = 31536372
79 + 31536293 = 31536372
149 + 31536223 = 31536372
211 + 31536161 = 31536372
271 + 31536101 = 31536372

Showing the first eight; more decompositions exist.
