Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33537816, here are decompositions:

7 + 33537809 = 33537816
19 + 33537797 = 33537816
47 + 33537769 = 33537816
107 + 33537709 = 33537816
127 + 33537689 = 33537816
139 + 33537677 = 33537816
223 + 33537593 = 33537816
227 + 33537589 = 33537816

Showing the first eight; more decompositions exist.
