Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33545100, here are decompositions:

73 + 33545027 = 33545100
79 + 33545021 = 33545100
101 + 33544999 = 33545100
103 + 33544997 = 33545100
107 + 33544993 = 33545100
151 + 33544949 = 33545100
179 + 33544921 = 33545100
223 + 33544877 = 33545100

Showing the first eight; more decompositions exist.
