Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532406, here are decompositions:

5 + 31532401 = 31532406
53 + 31532353 = 31532406
67 + 31532339 = 31532406
83 + 31532323 = 31532406
127 + 31532279 = 31532406
137 + 31532269 = 31532406
179 + 31532227 = 31532406
197 + 31532209 = 31532406

Showing the first eight; more decompositions exist.
