Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33507930, here are decompositions:

7 + 33507923 = 33507930
17 + 33507913 = 33507930
19 + 33507911 = 33507930
23 + 33507907 = 33507930
31 + 33507899 = 33507930
37 + 33507893 = 33507930
41 + 33507889 = 33507930
109 + 33507821 = 33507930

Showing the first eight; more decompositions exist.
