Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33471378, here are decompositions:

19 + 33471359 = 33471378
41 + 33471337 = 33471378
107 + 33471271 = 33471378
137 + 33471241 = 33471378
211 + 33471167 = 33471378
257 + 33471121 = 33471378
359 + 33471019 = 33471378
379 + 33470999 = 33471378

Showing the first eight; more decompositions exist.
