Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524450, here are decompositions:

31 + 31524419 = 31524450
47 + 31524403 = 31524450
107 + 31524343 = 31524450
149 + 31524301 = 31524450
157 + 31524293 = 31524450
173 + 31524277 = 31524450
179 + 31524271 = 31524450
193 + 31524257 = 31524450

Showing the first eight; more decompositions exist.
