Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33478000, here are decompositions:

29 + 33477971 = 33478000
71 + 33477929 = 33478000
317 + 33477683 = 33478000
401 + 33477599 = 33478000
509 + 33477491 = 33478000
587 + 33477413 = 33478000
653 + 33477347 = 33478000
683 + 33477317 = 33478000

Showing the first eight; more decompositions exist.
