Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33572994, here are decompositions:

11 + 33572983 = 33572994
23 + 33572971 = 33572994
53 + 33572941 = 33572994
61 + 33572933 = 33572994
67 + 33572927 = 33572994
73 + 33572921 = 33572994
83 + 33572911 = 33572994
97 + 33572897 = 33572994

Showing the first eight; more decompositions exist.
