Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33579280, here are decompositions:

3 + 33579277 = 33579280
23 + 33579257 = 33579280
71 + 33579209 = 33579280
101 + 33579179 = 33579280
167 + 33579113 = 33579280
179 + 33579101 = 33579280
191 + 33579089 = 33579280
227 + 33579053 = 33579280

Showing the first eight; more decompositions exist.
