Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678388, here are decompositions:

29 + 8678359 = 8678388
151 + 8678237 = 8678388
227 + 8678161 = 8678388
239 + 8678149 = 8678388
241 + 8678147 = 8678388
307 + 8678081 = 8678388
331 + 8678057 = 8678388
337 + 8678051 = 8678388

Showing the first eight; more decompositions exist.
