Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33578942, here are decompositions:

31 + 33578911 = 33578942
79 + 33578863 = 33578942
181 + 33578761 = 33578942
193 + 33578749 = 33578942
283 + 33578659 = 33578942
373 + 33578569 = 33578942
409 + 33578533 = 33578942
433 + 33578509 = 33578942

Showing the first eight; more decompositions exist.
