Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33581166, here are decompositions:

19 + 33581147 = 33581166
43 + 33581123 = 33581166
67 + 33581099 = 33581166
79 + 33581087 = 33581166
139 + 33581027 = 33581166
173 + 33580993 = 33581166
257 + 33580909 = 33581166
263 + 33580903 = 33581166

Showing the first eight; more decompositions exist.
