Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33490280, here are decompositions:

67 + 33490213 = 33490280
73 + 33490207 = 33490280
79 + 33490201 = 33490280
97 + 33490183 = 33490280
223 + 33490057 = 33490280
277 + 33490003 = 33490280
337 + 33489943 = 33490280
349 + 33489931 = 33490280

Showing the first eight; more decompositions exist.
