Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8725558, here are decompositions:

11 + 8725547 = 8725558
47 + 8725511 = 8725558
59 + 8725499 = 8725558
137 + 8725421 = 8725558
167 + 8725391 = 8725558
197 + 8725361 = 8725558
239 + 8725319 = 8725558
251 + 8725307 = 8725558

Showing the first eight; more decompositions exist.
