Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33545980, here are decompositions:

29 + 33545951 = 33545980
47 + 33545933 = 33545980
53 + 33545927 = 33545980
191 + 33545789 = 33545980
197 + 33545783 = 33545980
233 + 33545747 = 33545980
257 + 33545723 = 33545980
383 + 33545597 = 33545980

Showing the first eight; more decompositions exist.
