Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33491860, here are decompositions:

11 + 33491849 = 33491860
23 + 33491837 = 33491860
29 + 33491831 = 33491860
113 + 33491747 = 33491860
131 + 33491729 = 33491860
167 + 33491693 = 33491860
179 + 33491681 = 33491860
239 + 33491621 = 33491860

Showing the first eight; more decompositions exist.
