Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8661070, here are decompositions:

23 + 8661047 = 8661070
83 + 8660987 = 8661070
101 + 8660969 = 8661070
137 + 8660933 = 8661070
149 + 8660921 = 8661070
179 + 8660891 = 8661070
251 + 8660819 = 8661070
317 + 8660753 = 8661070

Showing the first eight; more decompositions exist.
