Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33478880, here are decompositions:

3 + 33478877 = 33478880
73 + 33478807 = 33478880
157 + 33478723 = 33478880
199 + 33478681 = 33478880
229 + 33478651 = 33478880
271 + 33478609 = 33478880
349 + 33478531 = 33478880
607 + 33478273 = 33478880

Showing the first eight; more decompositions exist.
