Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33578778, here are decompositions:

5 + 33578773 = 33578778
11 + 33578767 = 33578778
17 + 33578761 = 33578778
29 + 33578749 = 33578778
31 + 33578747 = 33578778
71 + 33578707 = 33578778
127 + 33578651 = 33578778
137 + 33578641 = 33578778

Showing the first eight; more decompositions exist.
