Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33549450, here are decompositions:

19 + 33549431 = 33549450
23 + 33549427 = 33549450
47 + 33549403 = 33549450
73 + 33549377 = 33549450
97 + 33549353 = 33549450
101 + 33549349 = 33549450
113 + 33549337 = 33549450
127 + 33549323 = 33549450

Showing the first eight; more decompositions exist.
