Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33557128, here are decompositions:

41 + 33557087 = 33557128
71 + 33557057 = 33557128
167 + 33556961 = 33557128
191 + 33556937 = 33557128
239 + 33556889 = 33557128
251 + 33556877 = 33557128
281 + 33556847 = 33557128
317 + 33556811 = 33557128

Showing the first eight; more decompositions exist.
