Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533214, here are decompositions:

5 + 31533209 = 31533214
23 + 31533191 = 31533214
47 + 31533167 = 31533214
71 + 31533143 = 31533214
113 + 31533101 = 31533214
233 + 31532981 = 31533214
347 + 31532867 = 31533214
521 + 31532693 = 31533214

Showing the first eight; more decompositions exist.
