Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8627940, here are decompositions:

29 + 8627911 = 8627940
31 + 8627909 = 8627940
37 + 8627903 = 8627940
43 + 8627897 = 8627940
47 + 8627893 = 8627940
73 + 8627867 = 8627940
89 + 8627851 = 8627940
107 + 8627833 = 8627940

Showing the first eight; more decompositions exist.
