Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33478668, here are decompositions:

17 + 33478651 = 33478668
19 + 33478649 = 33478668
59 + 33478609 = 33478668
61 + 33478607 = 33478668
107 + 33478561 = 33478668
137 + 33478531 = 33478668
151 + 33478517 = 33478668
191 + 33478477 = 33478668

Showing the first eight; more decompositions exist.
