Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678994, here are decompositions:

31 + 8678963 = 8678994
43 + 8678951 = 8678994
47 + 8678947 = 8678994
53 + 8678941 = 8678994
61 + 8678933 = 8678994
67 + 8678927 = 8678994
101 + 8678893 = 8678994
131 + 8678863 = 8678994

Showing the first eight; more decompositions exist.
