Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33507942, here are decompositions:

5 + 33507937 = 33507942
19 + 33507923 = 33507942
29 + 33507913 = 33507942
31 + 33507911 = 33507942
43 + 33507899 = 33507942
53 + 33507889 = 33507942
89 + 33507853 = 33507942
163 + 33507779 = 33507942

Showing the first eight; more decompositions exist.
