Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33581458, here are decompositions:

17 + 33581441 = 33581458
47 + 33581411 = 33581458
107 + 33581351 = 33581458
137 + 33581321 = 33581458
167 + 33581291 = 33581458
179 + 33581279 = 33581458
191 + 33581267 = 33581458
311 + 33581147 = 33581458

Showing the first eight; more decompositions exist.
