Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678946, here are decompositions:

5 + 8678941 = 8678946
7 + 8678939 = 8678946
13 + 8678933 = 8678946
19 + 8678927 = 8678946
43 + 8678903 = 8678946
47 + 8678899 = 8678946
53 + 8678893 = 8678946
83 + 8678863 = 8678946

Showing the first eight; more decompositions exist.
