Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33557312, here are decompositions:

109 + 33557203 = 33557312
181 + 33557131 = 33557312
193 + 33557119 = 33557312
211 + 33557101 = 33557312
409 + 33556903 = 33557312
433 + 33556879 = 33557312
601 + 33556711 = 33557312
631 + 33556681 = 33557312

Showing the first eight; more decompositions exist.
