Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33490240, here are decompositions:

29 + 33490211 = 33490240
59 + 33490181 = 33490240
131 + 33490109 = 33490240
149 + 33490091 = 33490240
167 + 33490073 = 33490240
197 + 33490043 = 33490240
233 + 33490007 = 33490240
263 + 33489977 = 33490240

Showing the first eight; more decompositions exist.
