Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33558978, here are decompositions:

29 + 33558949 = 33558978
41 + 33558937 = 33558978
127 + 33558851 = 33558978
137 + 33558841 = 33558978
227 + 33558751 = 33558978
241 + 33558737 = 33558978
307 + 33558671 = 33558978
389 + 33558589 = 33558978

Showing the first eight; more decompositions exist.
