Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33549138, here are decompositions:

11 + 33549127 = 33549138
47 + 33549091 = 33549138
61 + 33549077 = 33549138
67 + 33549071 = 33549138
71 + 33549067 = 33549138
79 + 33549059 = 33549138
89 + 33549049 = 33549138
157 + 33548981 = 33549138

Showing the first eight; more decompositions exist.
