Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33520878, here are decompositions:

19 + 33520859 = 33520878
31 + 33520847 = 33520878
101 + 33520777 = 33520878
191 + 33520687 = 33520878
197 + 33520681 = 33520878
211 + 33520667 = 33520878
229 + 33520649 = 33520878
257 + 33520621 = 33520878

Showing the first eight; more decompositions exist.
