Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33581278, here are decompositions:

11 + 33581267 = 33581278
131 + 33581147 = 33581278
179 + 33581099 = 33581278
191 + 33581087 = 33581278
251 + 33581027 = 33581278
257 + 33581021 = 33581278
347 + 33580931 = 33581278
359 + 33580919 = 33581278

Showing the first eight; more decompositions exist.
