Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33489920, here are decompositions:

19 + 33489901 = 33489920
43 + 33489877 = 33489920
151 + 33489769 = 33489920
157 + 33489763 = 33489920
181 + 33489739 = 33489920
193 + 33489727 = 33489920
271 + 33489649 = 33489920
307 + 33489613 = 33489920

Showing the first eight; more decompositions exist.
