Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33481280, here are decompositions:

163 + 33481117 = 33481280
181 + 33481099 = 33481280
193 + 33481087 = 33481280
199 + 33481081 = 33481280
223 + 33481057 = 33481280
277 + 33481003 = 33481280
337 + 33480943 = 33481280
367 + 33480913 = 33481280

Showing the first eight; more decompositions exist.
