Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8600900, here are decompositions:

3 + 8600897 = 8600900
19 + 8600881 = 8600900
157 + 8600743 = 8600900
181 + 8600719 = 8600900
199 + 8600701 = 8600900
223 + 8600677 = 8600900
271 + 8600629 = 8600900
307 + 8600593 = 8600900

Showing the first eight; more decompositions exist.
