Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33557394, here are decompositions:

7 + 33557387 = 33557394
37 + 33557357 = 33557394
53 + 33557341 = 33557394
67 + 33557327 = 33557394
71 + 33557323 = 33557394
137 + 33557257 = 33557394
191 + 33557203 = 33557394
197 + 33557197 = 33557394

Showing the first eight; more decompositions exist.
