Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33581448, here are decompositions:

7 + 33581441 = 33581448
11 + 33581437 = 33581448
37 + 33581411 = 33581448
67 + 33581381 = 33581448
97 + 33581351 = 33581448
127 + 33581321 = 33581448
149 + 33581299 = 33581448
151 + 33581297 = 33581448

Showing the first eight; more decompositions exist.
