Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33527280, here are decompositions:

23 + 33527257 = 33527280
41 + 33527239 = 33527280
97 + 33527183 = 33527280
109 + 33527171 = 33527280
131 + 33527149 = 33527280
139 + 33527141 = 33527280
151 + 33527129 = 33527280
173 + 33527107 = 33527280

Showing the first eight; more decompositions exist.
