Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8661174, here are decompositions:

13 + 8661161 = 8661174
37 + 8661137 = 8661174
113 + 8661061 = 8661174
127 + 8661047 = 8661174
131 + 8661043 = 8661174
173 + 8661001 = 8661174
191 + 8660983 = 8661174
227 + 8660947 = 8661174

Showing the first eight; more decompositions exist.
