Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678558, here are decompositions:

199 + 8678359 = 8678558
379 + 8678179 = 8678558
397 + 8678161 = 8678558
409 + 8678149 = 8678558
547 + 8678011 = 8678558
607 + 8677951 = 8678558
787 + 8677771 = 8678558
877 + 8677681 = 8678558

Showing the first eight; more decompositions exist.
