Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33551172, here are decompositions:

43 + 33551129 = 33551172
59 + 33551113 = 33551172
73 + 33551099 = 33551172
131 + 33551041 = 33551172
139 + 33551033 = 33551172
191 + 33550981 = 33551172
223 + 33550949 = 33551172
233 + 33550939 = 33551172

Showing the first eight; more decompositions exist.
