Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33478680, here are decompositions:

29 + 33478651 = 33478680
31 + 33478649 = 33478680
71 + 33478609 = 33478680
73 + 33478607 = 33478680
97 + 33478583 = 33478680
149 + 33478531 = 33478680
163 + 33478517 = 33478680
211 + 33478469 = 33478680

Showing the first eight; more decompositions exist.
