Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33512880, here are decompositions:

7 + 33512873 = 33512880
41 + 33512839 = 33512880
43 + 33512837 = 33512880
73 + 33512807 = 33512880
97 + 33512783 = 33512880
101 + 33512779 = 33512880
127 + 33512753 = 33512880
157 + 33512723 = 33512880

Showing the first eight; more decompositions exist.
