Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533338, here are decompositions:

79 + 31533259 = 31533338
211 + 31533127 = 31533338
241 + 31533097 = 31533338
337 + 31533001 = 31533338
367 + 31532971 = 31533338
379 + 31532959 = 31533338
439 + 31532899 = 31533338
457 + 31532881 = 31533338

Showing the first eight; more decompositions exist.
