Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33520864, here are decompositions:

5 + 33520859 = 33520864
17 + 33520847 = 33520864
101 + 33520763 = 33520864
197 + 33520667 = 33520864
467 + 33520397 = 33520864
491 + 33520373 = 33520864
593 + 33520271 = 33520864
683 + 33520181 = 33520864

Showing the first eight; more decompositions exist.
