Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33543840, here are decompositions:

37 + 33543803 = 33543840
67 + 33543773 = 33543840
79 + 33543761 = 33543840
131 + 33543709 = 33543840
151 + 33543689 = 33543840
167 + 33543673 = 33543840
179 + 33543661 = 33543840
191 + 33543649 = 33543840

Showing the first eight; more decompositions exist.
