Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33497280, here are decompositions:

23 + 33497257 = 33497280
29 + 33497251 = 33497280
31 + 33497249 = 33497280
41 + 33497239 = 33497280
73 + 33497207 = 33497280
97 + 33497183 = 33497280
127 + 33497153 = 33497280
139 + 33497141 = 33497280

Showing the first eight; more decompositions exist.
