Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33581466, here are decompositions:

29 + 33581437 = 33581466
53 + 33581413 = 33581466
73 + 33581393 = 33581466
137 + 33581329 = 33581466
167 + 33581299 = 33581466
179 + 33581287 = 33581466
199 + 33581267 = 33581466
257 + 33581209 = 33581466

Showing the first eight; more decompositions exist.
