Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33557138, here are decompositions:

7 + 33557131 = 33557138
19 + 33557119 = 33557138
37 + 33557101 = 33557138
61 + 33557077 = 33557138
127 + 33557011 = 33557138
211 + 33556927 = 33557138
271 + 33556867 = 33557138
457 + 33556681 = 33557138

Showing the first eight; more decompositions exist.
