Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33528278, here are decompositions:

37 + 33528241 = 33528278
67 + 33528211 = 33528278
127 + 33528151 = 33528278
211 + 33528067 = 33528278
229 + 33528049 = 33528278
271 + 33528007 = 33528278
307 + 33527971 = 33528278
331 + 33527947 = 33528278

Showing the first eight; more decompositions exist.
