Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532274, here are decompositions:

5 + 31532269 = 31532274
13 + 31532261 = 31532274
47 + 31532227 = 31532274
71 + 31532203 = 31532274
107 + 31532167 = 31532274
157 + 31532117 = 31532274
211 + 31532063 = 31532274
271 + 31532003 = 31532274

Showing the first eight; more decompositions exist.
