Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678574, here are decompositions:

17 + 8678557 = 8678574
67 + 8678507 = 8678574
101 + 8678473 = 8678574
127 + 8678447 = 8678574
181 + 8678393 = 8678574
211 + 8678363 = 8678574
241 + 8678333 = 8678574
251 + 8678323 = 8678574

Showing the first eight; more decompositions exist.
