Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533332, here are decompositions:

73 + 31533259 = 31533332
199 + 31533133 = 31533332
241 + 31533091 = 31533332
331 + 31533001 = 31533332
373 + 31532959 = 31533332
409 + 31532923 = 31533332
433 + 31532899 = 31533332
499 + 31532833 = 31533332

Showing the first eight; more decompositions exist.
