Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33581578, here are decompositions:

5 + 33581573 = 33581578
137 + 33581441 = 33581578
167 + 33581411 = 33581578
197 + 33581381 = 33581578
227 + 33581351 = 33581578
257 + 33581321 = 33581578
281 + 33581297 = 33581578
311 + 33581267 = 33581578

Showing the first eight; more decompositions exist.
