Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533398, here are decompositions:

19 + 31533379 = 31533398
139 + 31533259 = 31533398
271 + 31533127 = 31533398
307 + 31533091 = 31533398
397 + 31533001 = 31533398
439 + 31532959 = 31533398
499 + 31532899 = 31533398
661 + 31532737 = 31533398

Showing the first eight; more decompositions exist.
