Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33578166, here are decompositions:

19 + 33578147 = 33578166
47 + 33578119 = 33578166
59 + 33578107 = 33578166
67 + 33578099 = 33578166
79 + 33578087 = 33578166
163 + 33578003 = 33578166
199 + 33577967 = 33578166
227 + 33577939 = 33578166

Showing the first eight; more decompositions exist.
