Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532536, here are decompositions:

29 + 31532507 = 31532536
47 + 31532489 = 31532536
59 + 31532477 = 31532536
107 + 31532429 = 31532536
197 + 31532339 = 31532536
257 + 31532279 = 31532536
317 + 31532219 = 31532536
419 + 31532117 = 31532536

Showing the first eight; more decompositions exist.
