Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33557880, here are decompositions:

43 + 33557837 = 33557880
53 + 33557827 = 33557880
71 + 33557809 = 33557880
73 + 33557807 = 33557880
113 + 33557767 = 33557880
127 + 33557753 = 33557880
131 + 33557749 = 33557880
149 + 33557731 = 33557880

Showing the first eight; more decompositions exist.
