Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33485880, here are decompositions:

7 + 33485873 = 33485880
13 + 33485867 = 33485880
41 + 33485839 = 33485880
47 + 33485833 = 33485880
59 + 33485821 = 33485880
61 + 33485819 = 33485880
89 + 33485791 = 33485880
101 + 33485779 = 33485880

Showing the first eight; more decompositions exist.
