Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33572868, here are decompositions:

5 + 33572863 = 33572868
11 + 33572857 = 33572868
19 + 33572849 = 33572868
41 + 33572827 = 33572868
89 + 33572779 = 33572868
127 + 33572741 = 33572868
167 + 33572701 = 33572868
181 + 33572687 = 33572868

Showing the first eight; more decompositions exist.
