Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33557720, here are decompositions:

13 + 33557707 = 33557720
19 + 33557701 = 33557720
37 + 33557683 = 33557720
103 + 33557617 = 33557720
199 + 33557521 = 33557720
211 + 33557509 = 33557720
307 + 33557413 = 33557720
379 + 33557341 = 33557720

Showing the first eight; more decompositions exist.
