Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33490372, here are decompositions:

11 + 33490361 = 33490372
29 + 33490343 = 33490372
101 + 33490271 = 33490372
131 + 33490241 = 33490372
191 + 33490181 = 33490372
263 + 33490109 = 33490372
281 + 33490091 = 33490372
431 + 33489941 = 33490372

Showing the first eight; more decompositions exist.
