Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33549438, here are decompositions:

7 + 33549431 = 33549438
11 + 33549427 = 33549438
61 + 33549377 = 33549438
79 + 33549359 = 33549438
89 + 33549349 = 33549438
101 + 33549337 = 33549438
127 + 33549311 = 33549438
149 + 33549289 = 33549438

Showing the first eight; more decompositions exist.
