Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8657940, here are decompositions:

7 + 8657933 = 8657940
13 + 8657927 = 8657940
17 + 8657923 = 8657940
37 + 8657903 = 8657940
59 + 8657881 = 8657940
89 + 8657851 = 8657940
107 + 8657833 = 8657940
113 + 8657827 = 8657940

Showing the first eight; more decompositions exist.
