Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33572978, here are decompositions:

7 + 33572971 = 33572978
37 + 33572941 = 33572978
67 + 33572911 = 33572978
97 + 33572881 = 33572978
151 + 33572827 = 33572978
199 + 33572779 = 33572978
277 + 33572701 = 33572978
331 + 33572647 = 33572978

Showing the first eight; more decompositions exist.
