Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33520788, here are decompositions:

5 + 33520783 = 33520788
11 + 33520777 = 33520788
29 + 33520759 = 33520788
79 + 33520709 = 33520788
101 + 33520687 = 33520788
107 + 33520681 = 33520788
139 + 33520649 = 33520788
167 + 33520621 = 33520788

Showing the first eight; more decompositions exist.
