Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678236, here are decompositions:

23 + 8678213 = 8678236
89 + 8678147 = 8678236
107 + 8678129 = 8678236
167 + 8678069 = 8678236
173 + 8678063 = 8678236
179 + 8678057 = 8678236
197 + 8678039 = 8678236
257 + 8677979 = 8678236

Showing the first eight; more decompositions exist.
