Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33471390, here are decompositions:

31 + 33471359 = 33471390
37 + 33471353 = 33471390
47 + 33471343 = 33471390
53 + 33471337 = 33471390
67 + 33471323 = 33471390
103 + 33471287 = 33471390
149 + 33471241 = 33471390
167 + 33471223 = 33471390

Showing the first eight; more decompositions exist.
