Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33471440, here are decompositions:

3 + 33471437 = 33471440
7 + 33471433 = 33471440
31 + 33471409 = 33471440
43 + 33471397 = 33471440
97 + 33471343 = 33471440
103 + 33471337 = 33471440
127 + 33471313 = 33471440
199 + 33471241 = 33471440

Showing the first eight; more decompositions exist.
