Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533448, here are decompositions:

17 + 31533431 = 31533448
59 + 31533389 = 31533448
179 + 31533269 = 31533448
239 + 31533209 = 31533448
257 + 31533191 = 31533448
281 + 31533167 = 31533448
347 + 31533101 = 31533448
449 + 31532999 = 31533448

Showing the first eight; more decompositions exist.
