Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678538, here are decompositions:

19 + 8678519 = 8678538
31 + 8678507 = 8678538
139 + 8678399 = 8678538
179 + 8678359 = 8678538
199 + 8678339 = 8678538
227 + 8678311 = 8678538
359 + 8678179 = 8678538
389 + 8678149 = 8678538

Showing the first eight; more decompositions exist.
