Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8710840, here are decompositions:

11 + 8710829 = 8710840
59 + 8710781 = 8710840
107 + 8710733 = 8710840
113 + 8710727 = 8710840
137 + 8710703 = 8710840
191 + 8710649 = 8710840
251 + 8710589 = 8710840
269 + 8710571 = 8710840

Showing the first eight; more decompositions exist.
