Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678988, here are decompositions:

37 + 8678951 = 8678988
41 + 8678947 = 8678988
47 + 8678941 = 8678988
61 + 8678927 = 8678988
89 + 8678899 = 8678988
137 + 8678851 = 8678988
167 + 8678821 = 8678988
211 + 8678777 = 8678988

Showing the first eight; more decompositions exist.
