Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33550986, here are decompositions:

5 + 33550981 = 33550986
19 + 33550967 = 33550986
37 + 33550949 = 33550986
47 + 33550939 = 33550986
137 + 33550849 = 33550986
199 + 33550787 = 33550986
229 + 33550757 = 33550986
257 + 33550729 = 33550986

Showing the first eight; more decompositions exist.
