Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33553128, here are decompositions:

71 + 33553057 = 33553128
79 + 33553049 = 33553128
101 + 33553027 = 33553128
127 + 33553001 = 33553128
179 + 33552949 = 33553128
181 + 33552947 = 33553128
269 + 33552859 = 33553128
317 + 33552811 = 33553128

Showing the first eight; more decompositions exist.
