Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33541778, here are decompositions:

7 + 33541771 = 33541778
79 + 33541699 = 33541778
157 + 33541621 = 33541778
199 + 33541579 = 33541778
241 + 33541537 = 33541778
271 + 33541507 = 33541778
577 + 33541201 = 33541778
607 + 33541171 = 33541778

Showing the first eight; more decompositions exist.
