Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33578920, here are decompositions:

3 + 33578917 = 33578920
29 + 33578891 = 33578920
41 + 33578879 = 33578920
59 + 33578861 = 33578920
113 + 33578807 = 33578920
173 + 33578747 = 33578920
227 + 33578693 = 33578920
233 + 33578687 = 33578920

Showing the first eight; more decompositions exist.
