Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33507090, here are decompositions:

11 + 33507079 = 33507090
31 + 33507059 = 33507090
53 + 33507037 = 33507090
61 + 33507029 = 33507090
193 + 33506897 = 33507090
233 + 33506857 = 33507090
269 + 33506821 = 33507090
271 + 33506819 = 33507090

Showing the first eight; more decompositions exist.
