Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532492, here are decompositions:

3 + 31532489 = 31532492
139 + 31532353 = 31532492
151 + 31532341 = 31532492
163 + 31532329 = 31532492
223 + 31532269 = 31532492
283 + 31532209 = 31532492
379 + 31532113 = 31532492
421 + 31532071 = 31532492

Showing the first eight; more decompositions exist.
