Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33516880, here are decompositions:

11 + 33516869 = 33516880
17 + 33516863 = 33516880
29 + 33516851 = 33516880
41 + 33516839 = 33516880
113 + 33516767 = 33516880
149 + 33516731 = 33516880
191 + 33516689 = 33516880
233 + 33516647 = 33516880

Showing the first eight; more decompositions exist.
