Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678184, here are decompositions:

5 + 8678179 = 8678184
23 + 8678161 = 8678184
37 + 8678147 = 8678184
43 + 8678141 = 8678184
71 + 8678113 = 8678184
101 + 8678083 = 8678184
103 + 8678081 = 8678184
127 + 8678057 = 8678184

Showing the first eight; more decompositions exist.
