Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33481278, here are decompositions:

31 + 33481247 = 33481278
179 + 33481099 = 33481278
191 + 33481087 = 33481278
197 + 33481081 = 33481278
211 + 33481067 = 33481278
241 + 33481037 = 33481278
251 + 33481027 = 33481278
307 + 33480971 = 33481278

Showing the first eight; more decompositions exist.
