Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33578940, here are decompositions:

7 + 33578933 = 33578940
23 + 33578917 = 33578940
29 + 33578911 = 33578940
53 + 33578887 = 33578940
61 + 33578879 = 33578940
79 + 33578861 = 33578940
167 + 33578773 = 33578940
173 + 33578767 = 33578940

Showing the first eight; more decompositions exist.
