Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33581572, here are decompositions:

131 + 33581441 = 33581572
179 + 33581393 = 33581572
191 + 33581381 = 33581572
251 + 33581321 = 33581572
281 + 33581291 = 33581572
293 + 33581279 = 33581572
449 + 33581123 = 33581572
641 + 33580931 = 33581572

Showing the first eight; more decompositions exist.
