Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33278, here are decompositions:

31 + 33247 = 33278
67 + 33211 = 33278
79 + 33199 = 33278
97 + 33181 = 33278
127 + 33151 = 33278
229 + 33049 = 33278
241 + 33037 = 33278
307 + 32971 = 33278

Showing the first eight; more decompositions exist.
