Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33578772, here are decompositions:

5 + 33578767 = 33578772
11 + 33578761 = 33578772
23 + 33578749 = 33578772
79 + 33578693 = 33578772
89 + 33578683 = 33578772
113 + 33578659 = 33578772
131 + 33578641 = 33578772
173 + 33578599 = 33578772

Showing the first eight; more decompositions exist.
