Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33493280, here are decompositions:

97 + 33493183 = 33493280
109 + 33493171 = 33493280
127 + 33493153 = 33493280
199 + 33493081 = 33493280
277 + 33493003 = 33493280
283 + 33492997 = 33493280
409 + 33492871 = 33493280
433 + 33492847 = 33493280

Showing the first eight; more decompositions exist.
