Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33573978, here are decompositions:

7 + 33573971 = 33573978
19 + 33573959 = 33573978
29 + 33573949 = 33573978
71 + 33573907 = 33573978
89 + 33573889 = 33573978
101 + 33573877 = 33573978
149 + 33573829 = 33573978
157 + 33573821 = 33573978

Showing the first eight; more decompositions exist.
