Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8717900, here are decompositions:

19 + 8717881 = 8717900
31 + 8717869 = 8717900
43 + 8717857 = 8717900
97 + 8717803 = 8717900
109 + 8717791 = 8717900
127 + 8717773 = 8717900
151 + 8717749 = 8717900
157 + 8717743 = 8717900

Showing the first eight; more decompositions exist.
