Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33523840, here are decompositions:

3 + 33523837 = 33523840
11 + 33523829 = 33523840
41 + 33523799 = 33523840
47 + 33523793 = 33523840
59 + 33523781 = 33523840
71 + 33523769 = 33523840
83 + 33523757 = 33523840
89 + 33523751 = 33523840

Showing the first eight; more decompositions exist.
