Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33555172, here are decompositions:

5 + 33555167 = 33555172
23 + 33555149 = 33555172
41 + 33555131 = 33555172
71 + 33555101 = 33555172
83 + 33555089 = 33555172
179 + 33554993 = 33555172
269 + 33554903 = 33555172
281 + 33554891 = 33555172

Showing the first eight; more decompositions exist.
