Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33528380, here are decompositions:

3 + 33528377 = 33528380
7 + 33528373 = 33528380
13 + 33528367 = 33528380
19 + 33528361 = 33528380
43 + 33528337 = 33528380
73 + 33528307 = 33528380
139 + 33528241 = 33528380
229 + 33528151 = 33528380

Showing the first eight; more decompositions exist.
