Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33557972, here are decompositions:

31 + 33557941 = 33557972
61 + 33557911 = 33557972
73 + 33557899 = 33557972
79 + 33557893 = 33557972
163 + 33557809 = 33557972
223 + 33557749 = 33557972
241 + 33557731 = 33557972
271 + 33557701 = 33557972

Showing the first eight; more decompositions exist.
