Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33549378, here are decompositions:

19 + 33549359 = 33549378
29 + 33549349 = 33549378
41 + 33549337 = 33549378
59 + 33549319 = 33549378
67 + 33549311 = 33549378
89 + 33549289 = 33549378
97 + 33549281 = 33549378
127 + 33549251 = 33549378

Showing the first eight; more decompositions exist.
