Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8719000, here are decompositions:

47 + 8718953 = 8719000
83 + 8718917 = 8719000
113 + 8718887 = 8719000
131 + 8718869 = 8719000
149 + 8718851 = 8719000
167 + 8718833 = 8719000
197 + 8718803 = 8719000
263 + 8718737 = 8719000

Showing the first eight; more decompositions exist.
