Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678448, here are decompositions:

89 + 8678359 = 8678448
109 + 8678339 = 8678448
137 + 8678311 = 8678448
211 + 8678237 = 8678448
269 + 8678179 = 8678448
307 + 8678141 = 8678448
367 + 8678081 = 8678448
379 + 8678069 = 8678448

Showing the first eight; more decompositions exist.
