Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33545988, here are decompositions:

29 + 33545959 = 33545988
37 + 33545951 = 33545988
59 + 33545929 = 33545988
61 + 33545927 = 33545988
71 + 33545917 = 33545988
137 + 33545851 = 33545988
149 + 33545839 = 33545988
199 + 33545789 = 33545988

Showing the first eight; more decompositions exist.
