Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8661270, here are decompositions:

17 + 8661253 = 8661270
19 + 8661251 = 8661270
29 + 8661241 = 8661270
31 + 8661239 = 8661270
47 + 8661223 = 8661270
53 + 8661217 = 8661270
67 + 8661203 = 8661270
73 + 8661197 = 8661270

Showing the first eight; more decompositions exist.
