Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8661006, here are decompositions:

5 + 8661001 = 8661006
19 + 8660987 = 8661006
23 + 8660983 = 8661006
37 + 8660969 = 8661006
59 + 8660947 = 8661006
73 + 8660933 = 8661006
97 + 8660909 = 8661006
239 + 8660767 = 8661006

Showing the first eight; more decompositions exist.
