Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534492, here are decompositions:

5 + 31534487 = 31534492
149 + 31534343 = 31534492
191 + 31534301 = 31534492
251 + 31534241 = 31534492
293 + 31534199 = 31534492
389 + 31534103 = 31534492
419 + 31534073 = 31534492
569 + 31533923 = 31534492

Showing the first eight; more decompositions exist.
