Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33557942, here are decompositions:

31 + 33557911 = 33557942
43 + 33557899 = 33557942
193 + 33557749 = 33557942
211 + 33557731 = 33557942
241 + 33557701 = 33557942
421 + 33557521 = 33557942
433 + 33557509 = 33557942
601 + 33557341 = 33557942

Showing the first eight; more decompositions exist.
