Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33521880, here are decompositions:

17 + 33521863 = 33521880
19 + 33521861 = 33521880
37 + 33521843 = 33521880
53 + 33521827 = 33521880
59 + 33521821 = 33521880
83 + 33521797 = 33521880
97 + 33521783 = 33521880
127 + 33521753 = 33521880

Showing the first eight; more decompositions exist.
