Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33520920, here are decompositions:

29 + 33520891 = 33520920
61 + 33520859 = 33520920
73 + 33520847 = 33520920
107 + 33520813 = 33520920
137 + 33520783 = 33520920
157 + 33520763 = 33520920
211 + 33520709 = 33520920
233 + 33520687 = 33520920

Showing the first eight; more decompositions exist.
