Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33551978, here are decompositions:

7 + 33551971 = 33551978
139 + 33551839 = 33551978
181 + 33551797 = 33551978
241 + 33551737 = 33551978
349 + 33551629 = 33551978
601 + 33551377 = 33551978
661 + 33551317 = 33551978
769 + 33551209 = 33551978

Showing the first eight; more decompositions exist.
