Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33572840, here are decompositions:

13 + 33572827 = 33572840
61 + 33572779 = 33572840
97 + 33572743 = 33572840
127 + 33572713 = 33572840
139 + 33572701 = 33572840
157 + 33572683 = 33572840
193 + 33572647 = 33572840
211 + 33572629 = 33572840

Showing the first eight; more decompositions exist.
