Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33507120, here are decompositions:

11 + 33507109 = 33507120
13 + 33507107 = 33507120
41 + 33507079 = 33507120
61 + 33507059 = 33507120
83 + 33507037 = 33507120
173 + 33506947 = 33507120
223 + 33506897 = 33507120
263 + 33506857 = 33507120

Showing the first eight; more decompositions exist.
