Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532450, here are decompositions:

13 + 31532437 = 31532450
97 + 31532353 = 31532450
109 + 31532341 = 31532450
127 + 31532323 = 31532450
181 + 31532269 = 31532450
223 + 31532227 = 31532450
241 + 31532209 = 31532450
283 + 31532167 = 31532450

Showing the first eight; more decompositions exist.
