Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33508872, here are decompositions:

13 + 33508859 = 33508872
41 + 33508831 = 33508872
43 + 33508829 = 33508872
71 + 33508801 = 33508872
139 + 33508733 = 33508872
151 + 33508721 = 33508872
211 + 33508661 = 33508872
233 + 33508639 = 33508872

Showing the first eight; more decompositions exist.
