Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33557840, here are decompositions:

3 + 33557837 = 33557840
13 + 33557827 = 33557840
31 + 33557809 = 33557840
73 + 33557767 = 33557840
103 + 33557737 = 33557840
109 + 33557731 = 33557840
139 + 33557701 = 33557840
157 + 33557683 = 33557840

Showing the first eight; more decompositions exist.
