Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533196, here are decompositions:

5 + 31533191 = 31533196
29 + 31533167 = 31533196
47 + 31533149 = 31533196
53 + 31533143 = 31533196
197 + 31532999 = 31533196
257 + 31532939 = 31533196
419 + 31532777 = 31533196
503 + 31532693 = 31533196

Showing the first eight; more decompositions exist.
