Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8673558, here are decompositions:

11 + 8673547 = 8673558
41 + 8673517 = 8673558
59 + 8673499 = 8673558
137 + 8673421 = 8673558
139 + 8673419 = 8673558
181 + 8673377 = 8673558
197 + 8673361 = 8673558
199 + 8673359 = 8673558

Showing the first eight; more decompositions exist.
