Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33549780, here are decompositions:

7 + 33549773 = 33549780
23 + 33549757 = 33549780
53 + 33549727 = 33549780
97 + 33549683 = 33549780
107 + 33549673 = 33549780
109 + 33549671 = 33549780
113 + 33549667 = 33549780
149 + 33549631 = 33549780

Showing the first eight; more decompositions exist.
