Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33581000, here are decompositions:

7 + 33580993 = 33581000
43 + 33580957 = 33581000
97 + 33580903 = 33581000
109 + 33580891 = 33581000
151 + 33580849 = 33581000
181 + 33580819 = 33581000
199 + 33580801 = 33581000
223 + 33580777 = 33581000

Showing the first eight; more decompositions exist.
