Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33490208, here are decompositions:

7 + 33490201 = 33490208
19 + 33490189 = 33490208
151 + 33490057 = 33490208
229 + 33489979 = 33490208
277 + 33489931 = 33490208
307 + 33489901 = 33490208
331 + 33489877 = 33490208
337 + 33489871 = 33490208

Showing the first eight; more decompositions exist.
