Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8611000, here are decompositions:

3 + 8610997 = 8611000
107 + 8610893 = 8611000
137 + 8610863 = 8611000
149 + 8610851 = 8611000
173 + 8610827 = 8611000
197 + 8610803 = 8611000
263 + 8610737 = 8611000
269 + 8610731 = 8611000

Showing the first eight; more decompositions exist.
