Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33555142, here are decompositions:

11 + 33555131 = 33555142
41 + 33555101 = 33555142
53 + 33555089 = 33555142
149 + 33554993 = 33555142
191 + 33554951 = 33555142
239 + 33554903 = 33555142
251 + 33554891 = 33555142
293 + 33554849 = 33555142

Showing the first eight; more decompositions exist.
