Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8725588, here are decompositions:

17 + 8725571 = 8725588
41 + 8725547 = 8725588
89 + 8725499 = 8725588
107 + 8725481 = 8725588
167 + 8725421 = 8725588
191 + 8725397 = 8725588
197 + 8725391 = 8725588
227 + 8725361 = 8725588

Showing the first eight; more decompositions exist.
