Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33490390, here are decompositions:

29 + 33490361 = 33490390
47 + 33490343 = 33490390
53 + 33490337 = 33490390
149 + 33490241 = 33490390
179 + 33490211 = 33490390
281 + 33490109 = 33490390
293 + 33490097 = 33490390
317 + 33490073 = 33490390

Showing the first eight; more decompositions exist.
