Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33578988, here are decompositions:

11 + 33578977 = 33578988
19 + 33578969 = 33578988
71 + 33578917 = 33578988
97 + 33578891 = 33578988
101 + 33578887 = 33578988
109 + 33578879 = 33578988
127 + 33578861 = 33578988
181 + 33578807 = 33578988

Showing the first eight; more decompositions exist.
