Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533336, here are decompositions:

67 + 31533269 = 31533336
127 + 31533209 = 31533336
193 + 31533143 = 31533336
239 + 31533097 = 31533336
337 + 31532999 = 31533336
397 + 31532939 = 31533336
463 + 31532873 = 31533336
503 + 31532833 = 31533336

Showing the first eight; more decompositions exist.
