Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8665900, here are decompositions:

3 + 8665897 = 8665900
11 + 8665889 = 8665900
83 + 8665817 = 8665900
101 + 8665799 = 8665900
197 + 8665703 = 8665900
233 + 8665667 = 8665900
251 + 8665649 = 8665900
281 + 8665619 = 8665900

Showing the first eight; more decompositions exist.
