Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33520986, here are decompositions:

7 + 33520979 = 33520986
13 + 33520973 = 33520986
19 + 33520967 = 33520986
47 + 33520939 = 33520986
67 + 33520919 = 33520986
127 + 33520859 = 33520986
139 + 33520847 = 33520986
157 + 33520829 = 33520986

Showing the first eight; more decompositions exist.
