Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8661206, here are decompositions:

3 + 8661203 = 8661206
13 + 8661193 = 8661206
157 + 8661049 = 8661206
163 + 8661043 = 8661206
223 + 8660983 = 8661206
277 + 8660929 = 8661206
409 + 8660797 = 8661206
439 + 8660767 = 8661206

Showing the first eight; more decompositions exist.
