Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33520978, here are decompositions:

5 + 33520973 = 33520978
11 + 33520967 = 33520978
59 + 33520919 = 33520978
131 + 33520847 = 33520978
149 + 33520829 = 33520978
269 + 33520709 = 33520978
311 + 33520667 = 33520978
401 + 33520577 = 33520978

Showing the first eight; more decompositions exist.
