Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8712558, here are decompositions:

11 + 8712547 = 8712558
61 + 8712497 = 8712558
67 + 8712491 = 8712558
137 + 8712421 = 8712558
191 + 8712367 = 8712558
251 + 8712307 = 8712558
271 + 8712287 = 8712558
277 + 8712281 = 8712558

Showing the first eight; more decompositions exist.
