Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678398, here are decompositions:

5 + 8678393 = 8678398
59 + 8678339 = 8678398
251 + 8678147 = 8678398
257 + 8678141 = 8678398
269 + 8678129 = 8678398
317 + 8678081 = 8678398
347 + 8678051 = 8678398
359 + 8678039 = 8678398

Showing the first eight; more decompositions exist.
