Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33558990, here are decompositions:

11 + 33558979 = 33558990
41 + 33558949 = 33558990
53 + 33558937 = 33558990
67 + 33558923 = 33558990
139 + 33558851 = 33558990
149 + 33558841 = 33558990
229 + 33558761 = 33558990
239 + 33558751 = 33558990

Showing the first eight; more decompositions exist.
