Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33549690, here are decompositions:

7 + 33549683 = 33549690
17 + 33549673 = 33549690
19 + 33549671 = 33549690
23 + 33549667 = 33549690
29 + 33549661 = 33549690
59 + 33549631 = 33549690
89 + 33549601 = 33549690
113 + 33549577 = 33549690

Showing the first eight; more decompositions exist.
