Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33551988, here are decompositions:

5 + 33551983 = 33551988
11 + 33551977 = 33551988
17 + 33551971 = 33551988
31 + 33551957 = 33551988
79 + 33551909 = 33551988
139 + 33551849 = 33551988
149 + 33551839 = 33551988
191 + 33551797 = 33551988

Showing the first eight; more decompositions exist.
