Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33507940, here are decompositions:

3 + 33507937 = 33507940
17 + 33507923 = 33507940
29 + 33507911 = 33507940
41 + 33507899 = 33507940
47 + 33507893 = 33507940
131 + 33507809 = 33507940
197 + 33507743 = 33507940
251 + 33507689 = 33507940

Showing the first eight; more decompositions exist.
