Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33558018, here are decompositions:

19 + 33557999 = 33558018
31 + 33557987 = 33558018
37 + 33557981 = 33558018
97 + 33557921 = 33558018
101 + 33557917 = 33558018
107 + 33557911 = 33558018
127 + 33557891 = 33558018
139 + 33557879 = 33558018

Showing the first eight; more decompositions exist.
