Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33557642, here are decompositions:

229 + 33557413 = 33557642
439 + 33557203 = 33557642
499 + 33557143 = 33557642
523 + 33557119 = 33557642
541 + 33557101 = 33557642
631 + 33557011 = 33557642
673 + 33556969 = 33557642
739 + 33556903 = 33557642

Showing the first eight; more decompositions exist.
