Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33581308, here are decompositions:

11 + 33581297 = 33581308
17 + 33581291 = 33581308
29 + 33581279 = 33581308
41 + 33581267 = 33581308
191 + 33581117 = 33581308
281 + 33581027 = 33581308
317 + 33580991 = 33581308
389 + 33580919 = 33581308

Showing the first eight; more decompositions exist.
