Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33521100, here are decompositions:

13 + 33521087 = 33521100
17 + 33521083 = 33521100
43 + 33521057 = 33521100
61 + 33521039 = 33521100
79 + 33521021 = 33521100
97 + 33521003 = 33521100
113 + 33520987 = 33521100
127 + 33520973 = 33521100

Showing the first eight; more decompositions exist.
