Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33543280, here are decompositions:

41 + 33543239 = 33543280
107 + 33543173 = 33543280
131 + 33543149 = 33543280
263 + 33543017 = 33543280
293 + 33542987 = 33543280
317 + 33542963 = 33543280
479 + 33542801 = 33543280
503 + 33542777 = 33543280

Showing the first eight; more decompositions exist.
