Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33558784, here are decompositions:

11 + 33558773 = 33558784
23 + 33558761 = 33558784
47 + 33558737 = 33558784
107 + 33558677 = 33558784
113 + 33558671 = 33558784
263 + 33558521 = 33558784
353 + 33558431 = 33558784
443 + 33558341 = 33558784

Showing the first eight; more decompositions exist.
