Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33507666, here are decompositions:

19 + 33507647 = 33507666
43 + 33507623 = 33507666
67 + 33507599 = 33507666
89 + 33507577 = 33507666
103 + 33507563 = 33507666
163 + 33507503 = 33507666
223 + 33507443 = 33507666
307 + 33507359 = 33507666

Showing the first eight; more decompositions exist.
