Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33543678, here are decompositions:

5 + 33543673 = 33543678
17 + 33543661 = 33543678
29 + 33543649 = 33543678
37 + 33543641 = 33543678
101 + 33543577 = 33543678
131 + 33543547 = 33543678
139 + 33543539 = 33543678
149 + 33543529 = 33543678

Showing the first eight; more decompositions exist.
