Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33529808, here are decompositions:

19 + 33529789 = 33529808
61 + 33529747 = 33529808
97 + 33529711 = 33529808
139 + 33529669 = 33529808
199 + 33529609 = 33529808
307 + 33529501 = 33529808
421 + 33529387 = 33529808
439 + 33529369 = 33529808

Showing the first eight; more decompositions exist.
