Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33478018, here are decompositions:

5 + 33478013 = 33478018
17 + 33478001 = 33478018
47 + 33477971 = 33478018
89 + 33477929 = 33478018
137 + 33477881 = 33478018
359 + 33477659 = 33478018
419 + 33477599 = 33478018
491 + 33477527 = 33478018

Showing the first eight; more decompositions exist.
