Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33543818, here are decompositions:

109 + 33543709 = 33543818
157 + 33543661 = 33543818
241 + 33543577 = 33543818
271 + 33543547 = 33543818
307 + 33543511 = 33543818
331 + 33543487 = 33543818
337 + 33543481 = 33543818
379 + 33543439 = 33543818

Showing the first eight; more decompositions exist.
