Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33557146, here are decompositions:

3 + 33557143 = 33557146
59 + 33557087 = 33557146
83 + 33557063 = 33557146
89 + 33557057 = 33557146
137 + 33557009 = 33557146
257 + 33556889 = 33557146
269 + 33556877 = 33557146
587 + 33556559 = 33557146

Showing the first eight; more decompositions exist.
