Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33521168, here are decompositions:

181 + 33520987 = 33521168
229 + 33520939 = 33521168
277 + 33520891 = 33521168
367 + 33520801 = 33521168
409 + 33520759 = 33521168
487 + 33520681 = 33521168
547 + 33520621 = 33521168
607 + 33520561 = 33521168

Showing the first eight; more decompositions exist.
