Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33557666, here are decompositions:

3 + 33557663 = 33557666
157 + 33557509 = 33557666
199 + 33557467 = 33557666
349 + 33557317 = 33557666
409 + 33557257 = 33557666
463 + 33557203 = 33557666
523 + 33557143 = 33557666
547 + 33557119 = 33557666

Showing the first eight; more decompositions exist.
