Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33545920, here are decompositions:

3 + 33545917 = 33545920
101 + 33545819 = 33545920
131 + 33545789 = 33545920
137 + 33545783 = 33545920
173 + 33545747 = 33545920
197 + 33545723 = 33545920
227 + 33545693 = 33545920
263 + 33545657 = 33545920

Showing the first eight; more decompositions exist.
