Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33471438, here are decompositions:

5 + 33471433 = 33471438
29 + 33471409 = 33471438
41 + 33471397 = 33471438
79 + 33471359 = 33471438
101 + 33471337 = 33471438
151 + 33471287 = 33471438
167 + 33471271 = 33471438
197 + 33471241 = 33471438

Showing the first eight; more decompositions exist.
