Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8710640, here are decompositions:

7 + 8710633 = 8710640
13 + 8710627 = 8710640
19 + 8710621 = 8710640
31 + 8710609 = 8710640
73 + 8710567 = 8710640
157 + 8710483 = 8710640
181 + 8710459 = 8710640
199 + 8710441 = 8710640

Showing the first eight; more decompositions exist.
