Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8661164, here are decompositions:

3 + 8661161 = 8661164
103 + 8661061 = 8661164
163 + 8661001 = 8661164
181 + 8660983 = 8661164
277 + 8660887 = 8661164
367 + 8660797 = 8661164
397 + 8660767 = 8661164
541 + 8660623 = 8661164

Showing the first eight; more decompositions exist.
