Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33489840, here are decompositions:

11 + 33489829 = 33489840
71 + 33489769 = 33489840
101 + 33489739 = 33489840
103 + 33489737 = 33489840
113 + 33489727 = 33489840
127 + 33489713 = 33489840
151 + 33489689 = 33489840
157 + 33489683 = 33489840

Showing the first eight; more decompositions exist.
