Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33520672, here are decompositions:

5 + 33520667 = 33520672
23 + 33520649 = 33520672
233 + 33520439 = 33520672
389 + 33520283 = 33520672
401 + 33520271 = 33520672
431 + 33520241 = 33520672
491 + 33520181 = 33520672
503 + 33520169 = 33520672

Showing the first eight; more decompositions exist.
