Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33478820, here are decompositions:

13 + 33478807 = 33478820
61 + 33478759 = 33478820
97 + 33478723 = 33478820
127 + 33478693 = 33478820
139 + 33478681 = 33478820
211 + 33478609 = 33478820
409 + 33478411 = 33478820
433 + 33478387 = 33478820

Showing the first eight; more decompositions exist.
