Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33581548, here are decompositions:

107 + 33581441 = 33581548
137 + 33581411 = 33581548
167 + 33581381 = 33581548
197 + 33581351 = 33581548
227 + 33581321 = 33581548
251 + 33581297 = 33581548
257 + 33581291 = 33581548
269 + 33581279 = 33581548

Showing the first eight; more decompositions exist.
