Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8760640, here are decompositions:

11 + 8760629 = 8760640
17 + 8760623 = 8760640
107 + 8760533 = 8760640
137 + 8760503 = 8760640
173 + 8760467 = 8760640
179 + 8760461 = 8760640
191 + 8760449 = 8760640
347 + 8760293 = 8760640

Showing the first eight; more decompositions exist.
