Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678268, here are decompositions:

31 + 8678237 = 8678268
89 + 8678179 = 8678268
107 + 8678161 = 8678268
127 + 8678141 = 8678268
139 + 8678129 = 8678268
199 + 8678069 = 8678268
211 + 8678057 = 8678268
229 + 8678039 = 8678268

Showing the first eight; more decompositions exist.
