Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532510, here are decompositions:

3 + 31532507 = 31532510
13 + 31532497 = 31532510
73 + 31532437 = 31532510
109 + 31532401 = 31532510
157 + 31532353 = 31532510
181 + 31532329 = 31532510
241 + 31532269 = 31532510
283 + 31532227 = 31532510

Showing the first eight; more decompositions exist.
