Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33490242, here are decompositions:

29 + 33490213 = 33490242
31 + 33490211 = 33490242
41 + 33490201 = 33490242
53 + 33490189 = 33490242
59 + 33490183 = 33490242
61 + 33490181 = 33490242
151 + 33490091 = 33490242
199 + 33490043 = 33490242

Showing the first eight; more decompositions exist.
