Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33490188, here are decompositions:

5 + 33490183 = 33490188
7 + 33490181 = 33490188
79 + 33490109 = 33490188
97 + 33490091 = 33490188
131 + 33490057 = 33490188
157 + 33490031 = 33490188
181 + 33490007 = 33490188
211 + 33489977 = 33490188

Showing the first eight; more decompositions exist.
