Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33549442, here are decompositions:

11 + 33549431 = 33549442
83 + 33549359 = 33549442
89 + 33549353 = 33549442
131 + 33549311 = 33549442
191 + 33549251 = 33549442
359 + 33549083 = 33549442
383 + 33549059 = 33549442
461 + 33548981 = 33549442

Showing the first eight; more decompositions exist.
