Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33520840, here are decompositions:

11 + 33520829 = 33520840
131 + 33520709 = 33520840
173 + 33520667 = 33520840
191 + 33520649 = 33520840
263 + 33520577 = 33520840
401 + 33520439 = 33520840
443 + 33520397 = 33520840
467 + 33520373 = 33520840

Showing the first eight; more decompositions exist.
