Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678146, here are decompositions:

5 + 8678141 = 8678146
17 + 8678129 = 8678146
53 + 8678093 = 8678146
83 + 8678063 = 8678146
89 + 8678057 = 8678146
107 + 8678039 = 8678146
167 + 8677979 = 8678146
179 + 8677967 = 8678146

Showing the first eight; more decompositions exist.
