Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33551980, here are decompositions:

3 + 33551977 = 33551980
23 + 33551957 = 33551980
71 + 33551909 = 33551980
107 + 33551873 = 33551980
113 + 33551867 = 33551980
131 + 33551849 = 33551980
179 + 33551801 = 33551980
197 + 33551783 = 33551980

Showing the first eight; more decompositions exist.
