Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33553040, here are decompositions:

13 + 33553027 = 33553040
181 + 33552859 = 33553040
211 + 33552829 = 33553040
229 + 33552811 = 33553040
331 + 33552709 = 33553040
349 + 33552691 = 33553040
421 + 33552619 = 33553040
439 + 33552601 = 33553040

Showing the first eight; more decompositions exist.
