Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678940, here are decompositions:

7 + 8678933 = 8678940
13 + 8678927 = 8678940
37 + 8678903 = 8678940
41 + 8678899 = 8678940
47 + 8678893 = 8678940
89 + 8678851 = 8678940
107 + 8678833 = 8678940
157 + 8678783 = 8678940

Showing the first eight; more decompositions exist.
