Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33521000, here are decompositions:

13 + 33520987 = 33521000
61 + 33520939 = 33521000
109 + 33520891 = 33521000
157 + 33520843 = 33521000
199 + 33520801 = 33521000
223 + 33520777 = 33521000
241 + 33520759 = 33521000
313 + 33520687 = 33521000

Showing the first eight; more decompositions exist.
