Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533322, here are decompositions:

53 + 31533269 = 31533322
113 + 31533209 = 31533322
131 + 31533191 = 31533322
173 + 31533149 = 31533322
179 + 31533143 = 31533322
383 + 31532939 = 31533322
449 + 31532873 = 31533322
683 + 31532639 = 31533322

Showing the first eight; more decompositions exist.
