Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533256, here are decompositions:

47 + 31533209 = 31533256
89 + 31533167 = 31533256
107 + 31533149 = 31533256
113 + 31533143 = 31533256
137 + 31533119 = 31533256
257 + 31532999 = 31533256
317 + 31532939 = 31533256
383 + 31532873 = 31533256

Showing the first eight; more decompositions exist.
