Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33549372, here are decompositions:

13 + 33549359 = 33549372
19 + 33549353 = 33549372
23 + 33549349 = 33549372
53 + 33549319 = 33549372
61 + 33549311 = 33549372
83 + 33549289 = 33549372
89 + 33549283 = 33549372
139 + 33549233 = 33549372

Showing the first eight; more decompositions exist.
