Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33623880, here are decompositions:

13 + 33623867 = 33623880
23 + 33623857 = 33623880
29 + 33623851 = 33623880
41 + 33623839 = 33623880
47 + 33623833 = 33623880
61 + 33623819 = 33623880
83 + 33623797 = 33623880
89 + 33623791 = 33623880

Showing the first eight; more decompositions exist.
