Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33581880, here are decompositions:

11 + 33581869 = 33581880
19 + 33581861 = 33581880
23 + 33581857 = 33581880
43 + 33581837 = 33581880
61 + 33581819 = 33581880
67 + 33581813 = 33581880
89 + 33581791 = 33581880
113 + 33581767 = 33581880

Showing the first eight; more decompositions exist.
