Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33551840, here are decompositions:

43 + 33551797 = 33551840
67 + 33551773 = 33551840
103 + 33551737 = 33551840
109 + 33551731 = 33551840
163 + 33551677 = 33551840
211 + 33551629 = 33551840
307 + 33551533 = 33551840
313 + 33551527 = 33551840

Showing the first eight; more decompositions exist.
