Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33471640, here are decompositions:

11 + 33471629 = 33471640
47 + 33471593 = 33471640
107 + 33471533 = 33471640
149 + 33471491 = 33471640
281 + 33471359 = 33471640
317 + 33471323 = 33471640
353 + 33471287 = 33471640
467 + 33471173 = 33471640

Showing the first eight; more decompositions exist.
