Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524492, here are decompositions:

23 + 31524469 = 31524492
73 + 31524419 = 31524492
89 + 31524403 = 31524492
149 + 31524343 = 31524492
191 + 31524301 = 31524492
199 + 31524293 = 31524492
269 + 31524223 = 31524492
331 + 31524161 = 31524492

Showing the first eight; more decompositions exist.
