Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33507918, here are decompositions:

5 + 33507913 = 33507918
7 + 33507911 = 33507918
11 + 33507907 = 33507918
19 + 33507899 = 33507918
29 + 33507889 = 33507918
97 + 33507821 = 33507918
109 + 33507809 = 33507918
137 + 33507781 = 33507918

Showing the first eight; more decompositions exist.
