Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33578880, here are decompositions:

17 + 33578863 = 33578880
19 + 33578861 = 33578880
73 + 33578807 = 33578880
107 + 33578773 = 33578880
113 + 33578767 = 33578880
131 + 33578749 = 33578880
173 + 33578707 = 33578880
193 + 33578687 = 33578880

Showing the first eight; more decompositions exist.
