Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33585520, here are decompositions:

71 + 33585449 = 33585520
131 + 33585389 = 33585520
179 + 33585341 = 33585520
197 + 33585323 = 33585520
257 + 33585263 = 33585520
347 + 33585173 = 33585520
389 + 33585131 = 33585520
443 + 33585077 = 33585520

Showing the first eight; more decompositions exist.
