Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33549040, here are decompositions:

23 + 33549017 = 33549040
59 + 33548981 = 33549040
89 + 33548951 = 33549040
179 + 33548861 = 33549040
263 + 33548777 = 33549040
269 + 33548771 = 33549040
281 + 33548759 = 33549040
293 + 33548747 = 33549040

Showing the first eight; more decompositions exist.
