Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678148, here are decompositions:

7 + 8678141 = 8678148
19 + 8678129 = 8678148
67 + 8678081 = 8678148
79 + 8678069 = 8678148
97 + 8678051 = 8678148
109 + 8678039 = 8678148
137 + 8678011 = 8678148
181 + 8677967 = 8678148

Showing the first eight; more decompositions exist.
