Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33572988, here are decompositions:

5 + 33572983 = 33572988
17 + 33572971 = 33572988
47 + 33572941 = 33572988
61 + 33572927 = 33572988
67 + 33572921 = 33572988
107 + 33572881 = 33572988
131 + 33572857 = 33572988
139 + 33572849 = 33572988

Showing the first eight; more decompositions exist.
