Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33543780, here are decompositions:

7 + 33543773 = 33543780
19 + 33543761 = 33543780
71 + 33543709 = 33543780
107 + 33543673 = 33543780
131 + 33543649 = 33543780
139 + 33543641 = 33543780
197 + 33543583 = 33543780
227 + 33543553 = 33543780

Showing the first eight; more decompositions exist.
