Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33490028, here are decompositions:

67 + 33489961 = 33490028
97 + 33489931 = 33490028
127 + 33489901 = 33490028
151 + 33489877 = 33490028
157 + 33489871 = 33490028
199 + 33489829 = 33490028
379 + 33489649 = 33490028
409 + 33489619 = 33490028

Showing the first eight; more decompositions exist.
