Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33507128, here are decompositions:

7 + 33507121 = 33507128
19 + 33507109 = 33507128
181 + 33506947 = 33507128
271 + 33506857 = 33507128
307 + 33506821 = 33507128
331 + 33506797 = 33507128
439 + 33506689 = 33507128
541 + 33506587 = 33507128

Showing the first eight; more decompositions exist.
