Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33545028, here are decompositions:

7 + 33545021 = 33545028
29 + 33544999 = 33545028
31 + 33544997 = 33545028
79 + 33544949 = 33545028
89 + 33544939 = 33545028
107 + 33544921 = 33545028
131 + 33544897 = 33545028
151 + 33544877 = 33545028

Showing the first eight; more decompositions exist.
