Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8718900, here are decompositions:

13 + 8718887 = 8718900
19 + 8718881 = 8718900
23 + 8718877 = 8718900
31 + 8718869 = 8718900
41 + 8718859 = 8718900
61 + 8718839 = 8718900
67 + 8718833 = 8718900
89 + 8718811 = 8718900

Showing the first eight; more decompositions exist.
