Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678266, here are decompositions:

29 + 8678237 = 8678266
53 + 8678213 = 8678266
137 + 8678129 = 8678266
173 + 8678093 = 8678266
197 + 8678069 = 8678266
227 + 8678039 = 8678266
239 + 8678027 = 8678266
383 + 8677883 = 8678266

Showing the first eight; more decompositions exist.
