Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33489878, here are decompositions:

7 + 33489871 = 33489878
109 + 33489769 = 33489878
139 + 33489739 = 33489878
151 + 33489727 = 33489878
229 + 33489649 = 33489878
727 + 33489151 = 33489878
739 + 33489139 = 33489878
769 + 33489109 = 33489878

Showing the first eight; more decompositions exist.
