Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33549786, here are decompositions:

7 + 33549779 = 33549786
13 + 33549773 = 33549786
29 + 33549757 = 33549786
59 + 33549727 = 33549786
103 + 33549683 = 33549786
113 + 33549673 = 33549786
173 + 33549613 = 33549786
223 + 33549563 = 33549786

Showing the first eight; more decompositions exist.
