Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678238, here are decompositions:

59 + 8678179 = 8678238
89 + 8678149 = 8678238
97 + 8678141 = 8678238
109 + 8678129 = 8678238
157 + 8678081 = 8678238
181 + 8678057 = 8678238
199 + 8678039 = 8678238
211 + 8678027 = 8678238

Showing the first eight; more decompositions exist.
