Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33543978, here are decompositions:

7 + 33543971 = 33543978
79 + 33543899 = 33543978
101 + 33543877 = 33543978
137 + 33543841 = 33543978
269 + 33543709 = 33543978
317 + 33543661 = 33543978
337 + 33543641 = 33543978
401 + 33543577 = 33543978

Showing the first eight; more decompositions exist.
