Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8725670, here are decompositions:

13 + 8725657 = 8725670
43 + 8725627 = 8725670
61 + 8725609 = 8725670
103 + 8725567 = 8725670
139 + 8725531 = 8725670
181 + 8725489 = 8725670
211 + 8725459 = 8725670
241 + 8725429 = 8725670

Showing the first eight; more decompositions exist.
